I then used a PDF editor (PDF Exchange... not an endorsement, just what I had) to delete all the other pages. It's too big to attach here (21 kb). I did attach the view you get. The images remain crisp, so when you zoom, it works, even for the largest, busy screenshots. See attached.
You might also want to use a PDF in conjunction with the Web. Use the dynamic filtering to narrow to any visual changes you truly want to investigate.
Time investment for the work-around: less than five minutes.
