Quest 3 - A, B, X, Y mapping Fix Please ?

Like me, most sim racers will have many key commands mapped to buttons on their steering wheel.  All were easy to do EXCEPT the four controller buttons A, B, X & Y on the Quest controllers.  Please allow these to be mapped separately to a Wheel or other controller.  As it is now, to make adjustments it is necessary to pickup and put down the controllers constantly, as you would imagine that is a complete P.I.T.A. - an easy thing to overlook and hopefully simple to implement and fix !?  Thanks for finally releasing VR as from the beta it looks like it will be a ripper eventually. Cheers.
