A button to toggle crossplay On/Off

Recently there has been a huge hacking problem on the server side of mcbe, and i was wondering if it would be possible to add a button wich could toggle crossplay it would make gameplay more balanced for example a mobile player vs only mobile players or pc vs only pc, this would be very beneficial for our community, playing with players in different devices is awesome, dont get me wrong, but having to face them constantly can get tiring.
