Hi @catrionarobyn, Do you know how to use scripts? Try this one. Just make a selection and then run the script.

/** ------------------------------------------------------------------- *
* GET ITEMS *
* -------------------------------------------------------------------- *
* @author m1b *
* @version 2025-03-29 *
* -------------------------------------------------------------------- *
* Collects page items from a `from` source, eg. a Document, Layer, *
* GroupItem, or Array. Will look inside group items up to `maxDepth`. *
* Search can be filtered using `filter` function. Note that the *
* filter function is evaluated last in the filtering process. *
* -------------------------------------------------------------------- *
* Example 1. Get all items in document: *
* *
* var myItems = getItems({ from: app.activeDocument }); *
* *
* -------------------------------------------------------------------- *
* Example 2. Get all selected items except groups: *
* *
* var myItems = getItems({ *
* from: app.activeDocument.selection, *
* getGroupItems: false, *
* }); *
* *
* -------------------------------------------------------------------- *
* Example 3. Using `filter` function to choose item type: *
* *
* var myItems = getItems({ *
* from: app.activeDocument, *
* filter: function (item) { *
* return ( *
* 'PathItem' === item.typename *
* || 'CompoundPathItem' === item.typename *
* ); *
* } *
* }); *
* *
* -------------------------------------------------------------------- *
* Example 4. Using `filter` function: *
* *
* var myItems = getItems({ *
* from: app.activeDocument, *
* filter: onlyPngLinks *
* }); *
* *
* function onlyPngLinks(item, depth) { *
* return ( *
* 'PlacedItem' === item.typename *
* && '.png' === item.file.name.slice(-4).toLowerCase() *
* ); *
* }; *
* *
* -------------------------------------------------------------------- *
* Example 4. Using the `filter` function for custom collecting: *
* *
* This example bypasses the normal returned array and instead *
* captures items in an "external" array `itemsByDepth`. *
* *
* var itemsByDepth = []; *
* *
* function getItemsByDepth(item, depth) { *
* if (undefined == itemsByDepth[depth]) *
* itemsByDepth[depth] = []; *
* itemsByDepth[depth].push(item); *
* }; *
* *
* getItems({ *
* from: app.activeDocument, *
* filter: getItemsByDepth *
* }); *
* *
* -------------------------------------------------------------------- *
* @param {Object} options - parameters
* @param {PageItem|Array<PageItem>|Document|Layer} options.from - the thing(s) to look in, eg. a selection.
* @param {Function} [options.filter] - function that, given a found item, must return true (default: no filtering).
* @param {Boolean} [options.getPageItems] - whether to include page items in returned items (default: true).
* @param {Boolean} [options.getGroupItems] - whether to include GroupItems in returned items (default: true).
* @param {Boolean} [options.getLayers] - whether to include Layers in returned items (default: false).
* @param {Boolean} [options.getHiddenItems] - whether to include hidden items in returned items (default: true).
* @param {Boolean} [options.getLockedItems] - whether to include locked items in returned items (default: true).
* @param {Boolean} [options.getGuideItems] - whether to include guide items in returned items (default: false).
* @param {Number} [options.maxDepth] - deepest folder level (recursion depth limit) (default: 99).
* @param {Boolean} [options.returnFirstMatch] - whether to return only the first found item (default: false).
* @param {Number} [depth] - the current depth (private).
* @returns {Array|PageItem} - all the found items in a flat array, or the first found item if `returnFirstMatch`.
