Is it possible to map a button to swap between "normal" and "reverse" on a steering servo?

Hi everyone,

I have a rover with front and rear steering and I would like to be able to reverse the rear steering servo at will. Is there a way to map that to a button? I’ve been searching around and can’t find a way to do it, any help would be appreciated.

On your transmitter you can probably do this easily. I’m doing something kind of similar on my Rover for throttle. I don’t like center throttle neutral so I use a reverse switch.

I have been thinking about adding rear wheel steer to my Rover, I would be interested in seeing a photo of your vehicle.
