Does the API allow to move fields?

So I'm making an invoice template. It basically allows you to add as many fields as you want, along with notes for those fields and delete any fields. The issue is that as written you can only delete the most recent field. Otherwise, there's a big whole where the field used to be. I want to figure out a way to move all the fields after the deleted field up the appropriate amount. I know how the logic needs to look but I can't get it to work. Does the API allow you to move fields already on the document? Here's my code as of now 

```

var lineItemCount = 1;
var yTracker = 542;
var lineItemNoteMap = {};
var currentLineItem = 0;

function addLineItem() {
lineItemCount++;

// Define field names
var lineName = "lineItem " + lineItemCount;
var slugName = "lineItemSlug " + lineItemCount;
var rateName = "rate " + lineItemCount;
var hoursName = "hours " + lineItemCount;
var totalName = "total " + lineItemCount;

// Define y values
var line_uly = yTracker - 13;
var line_lry = line_uly - 21;

// Add Line Item field
this.addField(lineName, "text", 0, [228, line_uly, 365, line_lry]);
var lineItemProps = this.getField(lineName);
lineItemProps.textSize = 14;

// Add Line Item Slug field
var lineItemSlug = this.addField(slugName, "button", 0, [206.5, line_uly-4, 219.5, line_lry+4]);
lineItemSlug.buttonSetCaption (lineItemCount);
lineItemSlug.setAction ("MouseUp" , "deleteLineItem(" + lineItemCount + ")");
lineItemSlug.textColor = color.white;
lineItemSlug.textSize = 10;
var slug = this.addAnnot({
type: "Circle",
page: 0,
rect: [206.5, line_uly-4, 219.5, line_lry+4],
fillColor: ["CMYK" , .85, .72, .53, .59],
strokeColor: ["T"]
});

// Add rate field
this.addField(rateName, "text", 0, [419.615, line_uly, 474.815, line_lry]);
var rateFieldProps = this.getField(rateName);
rateFieldProps.textSize = 14;

// Add hours field
this.addField(hoursName, "text", 0, [494.615, line_uly, 549.815, line_lry]);
var hoursFieldProps = this.getField(hoursName);
hoursFieldProps.textSize = 14;

// Add total field
this.addField(totalName, "text", 0, [563.523, line_uly, 618.723, line_lry]);
var totalFieldProps = this.getField(totalName);
totalFieldProps.textSize = 14;

// update yTracker
yTracker = line_lry;
currentLineItem = lineItemCount;
}

var noteCount = 0;
function addNote() {
noteCount++;
var noteName = "Note " + noteCount;
var slugName = "Note Slug " + lineItemCount;
var note_ulx = 249;
var note_uly = yTracker - 5;
var note_lrx = 386;
var note_lry = note_uly - 10;
var slug_uly = note_uly - 3.5;
var slug_lry = note_lry + 3.5;
var base = Math.abs(slug_uly - slug_lry); // length of the base
var height = base / Math.sqrt(3); // height of the triangle
var slug_apex = [240.179 + height, (slug_lry + slug_uly) / 2]
var pointVertices = [[240.179,slug_lry],[240.179,slug_uly], slug_apex];
var noteText = this.addField(noteName, "text", 0, [note_ulx, note_uly, note_lrx, note_lry]);
noteText.textSize = 10;
var slug = this.addAnnot({
type: "Square",
page: 0,
rect: [228.179, slug_uly, 240.179, slug_lry],
fillColor: ["CMYK" , .85, .72, .53, .59],
strokeColor: ["T"],
width: [0
]
});
var slugPoint = this.addAnnot({
type: "Polygon",
page: 0,
vertices: pointVertices,
fillColor: ["CMYK" , .85, .72, .53, .59],
strokeColor: ["T"],
});
organizeNote(noteName);
yTracker = note_lry;
}

function deleteLineItem(index) {
// Names of the items to delete
var lineName = "lineItem " + index;
var slugName = "lineSlug " + index;
var rateName = "rate " + index;
var hoursName = "hours " + index; // Assuming similar naming for rate, hours and total fields
var totalName = "total " + index;

// Remove the items
this.removeField(lineName);
this.removeField(slugName);
this.removeField(rateName);
this.removeField(hoursName);
this.removeField(totalName);

// Getting number of notes associated with this line item
var notesCount = lineItemNoteMap[index] ? lineItemNoteMap[index].length : 0;

// Deleting the associated notes for this line item within lineItemNoteMap
if (notesCount > 0) {
lineItemNoteMap[index].forEach(noteName => {
this.removeField(noteName); // Remove the note fields
});

delete lineItemNoteMap[index]; // Remove the item from the map
}
// Calculate the required Y movement
// Replace "lineItemHeight" and "noteHeight" with actual heights, and "lineItemPadding" and "notePadding" with actual paddings
var offset = 34 + (notesCount *10) + (notesCount * 5);

// Adjust currentLineItem if necessary
currentLineItem = (currentLineItem === index) ? 0 : currentLineItem;
yTracker = yTracker + offset;
lineItemCount--;
}

function organizeNote(noteName) {
// currentLineItem holds the line item that notes should currently be associated with.
// lineItemNoteMap is the object holding arrays of notes for each line item.

if (lineItemNoteMap[currentLineItem]) {
// If current line item already has notes, just add the new note to its array
lineItemNoteMap[currentLineItem].push(noteName);
} else {
// If this is the first note for the current line item, start a new array
lineItemNoteMap[currentLineItem] = [noteName];
}
}
