is it possible to re-upload just a cover ?

I have noticed after the upload that my margins where off and some alignment, the book itself is fine just the cover needs an amendment, can I upload just a cover for a book? If so how?

Cheers

Hi,

Unfortunately, re-uploading just the Cover PDF or Pages PDF is not possible at this time.
If you notice something that needs an edit after upload, you will need to re-upload both elements as a new book. We are sorry for any inconvenience this may cause.

Thanks!
