Please expose a PDF's page count to scripting
To place a PDF in InDesign, you have to know the PDF's page count. The main point of the PlaceMultiPagePDF script is to show how you can place a PDF without knowing its page count, but it's slow business and get very tedious when you want to place part-ranges that include an open-ended range, such as 10-20, 30-
There is a hack, but it's ugly and unreliable.

Below a link to a thread that is showing a hack and other workarounds, that rely on software that is not InDesign:
"How can I get a total page count of a PDF before placing every page in the PDF?"
