Update Multiple Covers > Likes and Comments

Hi! I need to update the covers on three books (had a whole series recovered). ISBNs are:
978-0-9888547-0-3
978-0-9888547-5-8
978-1-7327027-0-7
I can't find a way to add an alternate cover, either.

Thanks!

We update covers only on Kindle and Audible editions, I have updated #1 & 3 for you.
#2 is an ebook edition, you can add an alternate cover edition using the [...] button

Thanks!
