CrossPlay Controller only Lobbies

Let PC players with controller play with other console players. Me and my brother use controller to play on PS4. After the update we decided to play together and downloaded the game on PC. But the player base of pc (in my region) is very low. Can you add an option to lock our input...for eg let pc players play with console players on console lobbies and he must use a controller to play or else he cant. Its the same thing happening in Warzone. Make 2 lobbies for crossplay if any one is using KeyBoard and mouse put the in K/M lobby if all are using controller put them in controller lobbies...Hope you will consider my suggestion and will come up with good solution.
