different page numbering for the same files

[Leah Smaller]

Good day mavins,

I have 2 books where book 1 uses files 1 - 10 and book 2 uses some of the same files (let's say files 5 - 7). 

I want to set up the books (files) so that in book 1 all the pages are numbered consecutively, starting from page 1 in file 1.  Thus the first page in file 5 will be, for instance, page 35. 

I also want the pages in book 2 to start from 1; here file 5 needs to start at page 1. 

How can I set up the numbering so this happens automatically and the page number in files 5 - 7 are appropriate in each book without requiring human intervention.

TIA,
