Editing published cover image?

Hello writers! Recently inspired to scrawl smut again, I published new material here recently (thanks to mods helping me get this account back!) and discover the new world of cover images. During the posting process I read that the cover can be edited within 90 days of publication, I think; but there doesn't seem to be an obvious way of doing that, besides recalling the story. Is that the way, or am I missing something? Thanks!

I believe you need to take the story into Edit mode, add/modify the cover image, then put a note to the Mods that that is all you did. When it is resubmitted, it will repost quickly.
