Correct way to allow multiple user inputs on single menu?

Hello!

What is the correct way to implement a multi-button menu (character select screen) that allows multiple inputs, such as 4 gamepads or a combination of gamepads and keyboard/mouse?

Does a Widget receive multiple player/controller inputs by default, as suggested by the function “Has User Focus”, which looks for a Player Controller Object? Or do you have to feed information to the Widget as to which controller is focusing on what element?

Thanks!
