Is it possible to use a keyboard and controller for local multiplayer?

So i followed the epic live stream tutorial about local multiplayer. I know that theres that checkbox which will automatically assign the controller to player 2 so the keyboard will always be player one, but, i noticed if that is unchecked then the keyboard is player 1, and when someone uses the controller, it deletes the already existing player and makes the controller player one. The reason this is an issue for me is because if theres only one controller, the game thinks there are 2 players and it screws up several things in the game. Does anyone have any suggestions on how to fix this? (sorry if the wording is confusing its hard to explain through text).
