This suggestion might seem odd to some, but it does feel like something that is worth implementing.
There's an option to pick "random skin" to have an random skin from your list picked for use every match, extra useful for the times you're playing with friends and don't want to be targeted N1 because they know who you are thanks to a skin you always use, or simply if you feel like switching it up and too lazy to change before every single match.
The thing is, that i, and i'm sure quite a few other people, wouldn't like to use an skin of the opposite gender, therefore an easy solution would just have 2 extra Random skins options - Random Male / Random Female.
Pretty sure it's also easy to design, as the devs can just add a sub-category to each skin - Male / Female.
And then attach Random Male/Female with the skins from that said category.
