Indesign: Reproducing a selection on a different page
I have a two page cover (front and back of a wrap around) where I'd like to reproduce the front page on a separate page, actively linked back to the appropriate section of the two-page. The idea being if something is updated on the two-page cover it automatically updates on the single-page as well. I feel I've seen this before, but I'm not finding the right terms to search for. Or am I just dreaming something up? I could of course, do a separate file and then link it into the other. Yet, if possible I'd minimise the amount of files drifting around to reduce confusion.
I'd appreciate any hints to do this or standard practices that flow into this way of working. Many thanks in advance!
