I have a front cover. The KDP back cover option when one already has a front cover seems only to be an author photo and some small type, followed by more small type. I'd like to eliminate both and put a headline on the back cover. Worst case, I want to eliminate the photo and the small type next to it and just have body text that is placed lower on the page at a larger size.
At one point I gave up and tried to create the back cover in Canva, but it seems to have changed its options and I'm not really looking for a learning curve.
Any quick and dirty solutions for someone who doesn't want to mess with Photoshop?
