Add Alternate Book Edition

[Brittanny]

Hello.
I’d like to update (by which I mean change the cover) for my paperback edition. I’m told here is where I request it. I know that you don’t change paperback covers. I only want to put the Kindle cover up where my ancient paperback cover is, bc the old paperback turns potential readers away. So, whatever the specific wording, I need an alternate edition of my book.
Can you help?
Thank you in advance,
Brittanny Davis
