to customize your slave??
you can do that via debug I think. you can also give them a haircut at the bathrooms don't know how much customizations you can do through that though.
have one mod in mind though you would have to find the right pawn to edit
mod name is B.O.O.P. you can freely edit any skin on any pawn just got to interact with them while wearing it. you can't edit the name but you can edit their gender and everything body wise even change their species
(reason why you got to find the right pawn to edit is because of the name unless you don't really care about the name of the pawn then have at it)
