Can I create more than one print trim for the same cover?
Yes. Every front-cover trim can become its own print-cover project. For example, you can keep separate 5 x 8 inch, 6 x 9 inch, A5, and custom-size paperback editions under the same book cover.
Select the matching front render when starting each project. The back cover, spine width, page count, and downloaded files are stored with that trim, so changes made for one size do not have to replace your other editions.
