KYF more settings to create "gamemodes"

I know that there are many other changes that would be high priority but I don't see many people ever talk about KYF. It would be nice to be able to do more changes to the match to create more game modes like for example being able to eliminate or make survivors take certain perks for challenges in game such as No Mither. Or add the option to add more than 1 killer or more than 4 survivors in kyf also.
