I have a 45pg document I want to print 2 sided. The front and back sides will be the same so I need to duplicate each page. So I would end up with page 1, page 1, page 2, page 2, etc. Obvioulsy doing this 45 times would be a pain so I select all the pages, hold down option, an duplicate. But of course it puts my duplicated 45 pages after the 1st 45 pages. So I end up with page 1-45, 1-45.
Is there anyway to duplicate all pages at once and have them in the order I need?
Thanks!
