Using File\Paste with a multi-page .pdf

Hello everyone,

I am running Adobe Reader in Creative Cloud on my PC, and Adobe Scan and Adobe Reader in my 7th gen. Apple iPad.  Further, forgive me if I am asking this in the wrong forum!  Maybe this question should go to the InDesign community, but as .pdfs are at the center of my question , I hope someone here has had the same experience to provide a solution.  Here is what's going on:

I scanned an old (1901) book into my iPad using Adobe Scan (really handy, btw).  The book is 40 pages, including covers.  Forty scans are too much for one .pdf, so I scanned the pages into five separate .pdf docs of nine pages or less apiece.  My ultimate goal is to create a a searchanble e-book in .pdf format from Adobe InDesign (ID) that can live in my iPad for reference/research purposes.   (Note: I borrowed the book from the owner, who lives some 1800 miles away.  Starting over with single-page scans in Adobe Scan would be wonderful and probably advised, but is not an option.  The book's paper is very fragile and I'm leery about having it mailed here.)

ID's File\Place function easily picks up the first page of a .pdf to drop in, but is there a way to use File\Place to search within a multi-page .pdf and pick up page 2, page 3 and so on?  It seems only page 1 can be picked up with File\Place.

To be able to use File\Place for all pages, I opened each of the multi-page .pdfs and created a separate .pdf of each page from the Print dialog box (choosing Adobe PDF).  No success.  Although the images in the single-page.pdfs came out smaller in size, the resulting .40-page pdf e-book became three times larger in size than the ID doc itself!  Pdfs just don't work this way!

Most bothered this morning by this outcome, I troubleshot the larger .pdf size and discovered that the newly created, single .pdfs are behind it. 

The only thing left was to open each multi-page .pdf and copy each page to paste into the ID doc.  (This procedure would make the ID forum people cringe, but...!)   My resulting e-book now is about 2/3 smaller than the ID doc, as it should be.  However, the ID doc is now much larger in size to get the smaller .pdf e-book.   Copy/Paste is not an ideal solution, but it did what I needed it to do.  SO....

I have been wondering, anyway, if it's possible to grab a page other than page 1 within a multi-page .pdf to File\Place into an ID doc.  Now the need to know is great.  Is there a way?   (If not, I have an idea about how to fashion it, but not the software know-now to make it happen.)

Thank you very much.
