Help with Player specific skin/character switch

What feature do you want to get added in?

Hello there Psych Online Github, I'm looking for help with a little experiment/feature I'm trying to do for a song pack of mine that I've been working on through the last couple of days.

Long story short, I'm trying to make it so in certain songs, the skins of one specific side change according to the events of a song, however, when doing the code like I'd normally do in Psych 0.6.1, the secondary player on the bf side will also switch, but instead of switching to their own alternative version of their skin, they'd take mine (Likely due to the way this stuff works when you don't specify which player on the bf side, which I've been trying to understand how to fix)

Is there a way to make character changes be specific to a player via lua code?

triggerEvent('Change Character', "bf1", "hahafunny1"); triggerEvent('Change Character', "bf2", "hahafunny1but2");

Side note: I know this might look like I'm asking for documentation but idk if the feature itself is a thing which is why I picked the feature request label instead (Sorry if that's messed up anyhow, I'm still kinda fresh with this site)
