how to change book measuremants and masterpage assignment?
so i formatted my book but i forgot to base it on the actual size of my cover art. so now i gotta find out how to change a documents measurements retroactively but also i have to find out how to fix my master pages cause i forgot to add a page for the cover and now my master pages are all flipped where all leftside pages use the rightside template and vice versa!
how do i fix both?
