Topic: ambient_gender tag????

There needs to be a tag for when a character of a specific gender is in the background of a piece, but isn't important to overall art. I can't be the only person who is annoyed by this. There's art that I really like that has a female character in the background, but doesn't show up normally because I have the female tag blacklisted. If there was a tag made for a gender in the background that doesn't conflict with the foreground, that'd be great. I don't know if this tag exists already but I've never seen it before.
