Setting joystick switches to re-center Aileron Trim

[BigT-65]

I am flying the Corsair in MSFS. During takeoff I set the rudder trim to +6 and the Aileron trim to +3. I have mapped a switch on my throttle control to re-center the rudder trim and it works but even though I have found commands for re-centering aileron trim in the MSFS controls settings I can't get any of them to work. For me it is very difficult while getting off the ground and flying to look down and turn the knob with my mouse. Surely this is doable since it can be done with the rudder trim and the elevator trim. Has anyone done this? It would be great to hear from you.
Thanks

This is the support area for the MSFS version:

I believe this forum was for the P3D version.

Sorry,
I didn't see any distinction between P3D and MSFS here. I went through the whole list of sub-forums listed but did not see one that specifically said it was MSFS. I will check the link you posted.
