I'm sure there might be a better name for this, but what about specific scenario tags? A viewer wants to see a specific character doing a specific thing. Say someone wants to see Krystal from Star Fox in a dominant role. A scenario tag could be something like character:krystal_domming

Something even more specific could be character:krystal_domming_character:renemon

I have a 100% certainty that this will never be implemented because of how niche it is, but just throwing it out there as a what-if. It'd be pretty cool imo
