Well, I can't speak for Paperport, although I am sure you can do just about anything with it.
With Adobe, you just open the document you were referring to, and then you set it where all of the pages are also in thumbnail view on the left. You can then drag and drop any of the thumbnails on the desktop, and they become separate PDFs. So, if the first three pages were Mr. Smith's, you just use the control key and click on each one and drag them out, and they are now one PDF.
I wish they didn't send them all together. At least we were able to negotiate with our lab, and they at least send a cover sheet with the names on them. We are the only ones they do this for. Pretty cool. All of our radiology faxes come separately.
