MultiPage pdf across multiple panel guide script

I need a script to place multi page pdf onto a guide outlined INDD page.  For instance.  I have label sheet blank, i make the guides to match the labels then run this script that places all the pages in the PDF into the guides for the labels. 

The only script i found places them each onto one page.  This won't work for filling out label sheets.  I'm fairly familiar with INDD but i'm not a trained user.

Please give me clear step by step instructions.

Thank you.
