Link a PDF with multiple pages to specific squares (rectangle) on my Indesign Page

Hi @Nimzi if you want to try some scripting, I've written out a little example that does basically what you ask. See what you think. Maybe you can adapt it to suit. - Mark

function main() {

    // ask user for a pdf/ai file

    var regex = /\.(ai|pdf)$/i,
        fsFilter = function (f) { return (regex.test(decodeURI(f.name)) || f.constructor.name == 'Folder') },
        file = File.openDialog("Please select a PDF or AI File", fsFilter, false);

    // place the pages

    var doc = app.activeDocument,
        rectangles = doc.pages[0].rectangles;

    for (var i = 0; i < rectangles.length; i++) {

        // attributes of the placed pdf
        app.pdfPlacePreferences.pageNumber = (i + 1);
        app.pdfPlacePreferences.pdfCrop = PDFCrop.CROP_TRIM;
        app.pdfPlacePreferences.transparentBackground = false;

        // place the page
        rectangles[i].place(file, false);

        if (
            i > 1
            && rectangles[i].graphics[0].pdfAttributes.pageNumber == 1
        ) {
            // when the page number reverts to "1"
            // there are no more pages in the pdf
            rectangles[i].graphics[0].remove();
            break;
        }

    }

}
app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, 'Place PDF Pages');

Edit 2023-05-19: typo in script. Oops.
