UMG Navigation with Arrow keys by default

So i’m currently making the UI for my game, and i’m trying to do a navigation that works both with keyboard and gamepad. I have a question though. If i press the arrow keys, even without any input setup for this, the focus of the buttons will automatically change accordingly.
That’s cool, but i now want to manipulate this event (i.e. Override the event and being able to bind it to other inputs)

How do i do this?

Thanks in advance.
