Multiple controller inputs

Fresh out the womb in terms of UE gamedev so keep that in mind.

I’m trying to create a character selection menu for up to four players.

If a controller is connected and a player presses the designated button they should be assigned a spot on the screen with their own widget menu to choose a character on.

However I can’t find a way to lock the player to just that part of the screen or to make it so the widget only accepts inputs from the designated controller.

Is there some easy way of making it so it only ever listens to inputs from a specified controller?
