Differential thrust for yaw in fbwa tilt/Tri

Looking for some information on differential thrust for yaw on a tilt/Tri quad plane. I can find info on how to configure for Plane, by setting servo params for left and right throttle, but on tilt/Tri quad plane the servo outputs are configured as motor 1 and 2. So was wondering if it’s possible to use differential thrust for yaw in quadplane? Thanks

I’m also curious if such an approach could be used on a twin quadplane, that is a quadplane with 4 lift motors and two forward flight motors. I’m really looking for a way to get yaw-authority in Q_ASSIST modes without a vertical fin or rudder.
