I am missing the following function in Indesign: You have, as an example, 100 pdf files, format A4, and you want to print them 2 on an A3 sheet, but in such a way that the pdfs number 1 to 50 are shown on the left in the file/paper, and on on the right the pdf's of nr 51-100. If you then cut the A3 in the middle, you have two piles with all the PDFs in order of number.
