Please allow editing video/media slugs

Because of my error, the file had the wrong name, and the slug was taken from the wrong name of the file... So I corrected de the name of video/media, BUT I couldn't edit the slug (I know I can make the change by DB, BUT, it's preferable having possibilty to edit the slug on FlluentPlayer).

I know you use the prefix "fluent-player-BUT-I-WANT-TO-EDIT-THIS-PART-OF-SLUG"

Thanks!
