Reply To: Is it possible for Indesign to auto relink to multi-page PDF file

That script is awesome.
Another option is to put 2 graphic frames on a master page, and set them to object > Fitting > Frame Fitting Options to “Fit Proportionally”
Then you can go back to the document page. Choose File > Place, select the PDF, and turn on Show Import Options. Choose to import all the pages from the PDF. Now you just need to click on the first frame, then the second, then press command-shift-P (or ctrl-shift-P) to add a new page, and then click-click again, and keep repeating that. It’s monotonous, but it’ll only take about 5 minutes.
