Five Figure Fanwork Exchange

I noticed X-Men (Movieverse) is already an approved fandom in the tagset. If I want to request a character as depicted in only a specific set of movies (the original timeline), is it better to nominate the OG timeline as a separate fandom, or to nominate under Movieverse and then DNW the alternate timeline (X-Men: First Class onward) in my optional details? Asking because that feels like a lot of canon to DNW. Thanks!
