Motion Controller Virtual Accept

In the InputCoreTypes class, the Gamepad_FaceButton_Bottom is set as Virtual Accept key.
Is there any way to set a motion controller button as Virtual Accept so it can trigger mouse click events?
I’d like to use my motion controller exactly as the xbox gamepad (navigating through UMG menues with the stick and clicking with a face button instead of the point and click method).

Cheers,
J
