EG doesn't already have one (and we can implement an option to replace the current EG's credits, maybe later on?).
yes, similar to mb
i'd say if it does not have one, jsut add to it, and if it dos and the edition is beig altered show a ticketbox to "also edit the artist credit of the EG"
but yes this can be done included while doing this for edition name as well so a separate thing
