Save multiple artboards as a single PDF page, not a PDF with multiple pages

Guys, this cript will do the job: 

// Prompt the user to select a destination folder
var destFolder = Folder.selectDialog("Select a destination folder for PDF exports.");

// Check if a folder was selected
if (destFolder != null) {
// Loop through all artboards and export to PDF
for (var i = 0; i < app.activeDocument.artboards.length; i++) {
// Set the current artboard
app.activeDocument.artboards.setActiveArtboardIndex(i);

// Get the current artboard's name
var artboardName = app.activeDocument.artboards[i].name;

// Create a new file object for the export
var exportFile = new File(destFolder + "/" + artboardName + ".pdf");

// Set the export options
var exportOptions = new PDFSaveOptions();
exportOptions.artboardRange = (i + 1).toString();
exportOptions.preserveEditability = false;

// Export the PDF
app.activeDocument.saveAs(exportFile, exportOptions);
}

// Alert the user that the export is complete
alert("Artboards have been exported as individual PDFs to " + destFolder + ".");
}
else {
// Alert the user that no folder was selected
alert("No destination folder was selected. Please try again.");
}

https://forums.adobe.com/people/Barbara+Ash  wrote Another approach. Position your 3 artboards horizontally so that they are touching each other. Draw a rectangle that covers all 3 artboards and arrange it to the back. It can be white with no stroke so that it doesn't show when printed. Choose File > Print and select the PDF print driver. In the print dialog, put a check mark on Ignore Artboards. Your file will print on a single PDF page.

Why do that when you can use Save a Copy, choose PDF and select just the artboard you want?

Thank you for the reply.

Yes, I can just create a another document with the dimensions of all the artboards I have now as one artboard, then copy and paste my art to that one artboard and save out a single page PDF. I wanted to avoid having to do that.

I guess there is no way to save out multiple artboards as a single page/single image?

Thanks again.
