Setting keyboard focus for a single screen in local splitscreen.

I currently have a splitscreen game setup in which one player is on mouse/keyboard and the other is on controller. I want to make a widget that allows an interacting player to navigate through a menu with either the mouse or the controller while allowing the other player to continue controlling the game as normal. Is there a way to do this in blueprints? When I use set keyboard focus, both players lose control of the game.
