WP Speed Change during Auto Mission via Variable RC switch Rover 4.4.0

Hello Community, I recently built and I’m currently using (with great success) an autonomous zero turn mower. (Exmark Lazer Z 52" 30HP).

I was tying to find a way to change the WP Speed via my RC remote during Auto missions.

Any pointers if this is possible, and how it is setup would be greatly appreciated.
