Devo F12E channel mapping

Hello. I have a Devo F12E and bought a Skyzone FPV Googles. My BIG problem is Skyzone map 4 channels to head tracking (aux 1, 2, 3 and 4) and these switches are on/off kind (gimbal control is aux 5 and 6). I tried to connect on aux 1 and 2 and the head traking works fine, but when I change trainer back to Devo I can't control the gimbal.

Is there any way to remap channel 5 and 6 (gimbal control knob) to 1 and 2, for example?

Thanks.

I'm using firmware 1.6A. My radio is new and I searched for a new fw and I think it"s the last released.
