In Arducopter you have more than one channel used to switch modes, 5 for most modes and 7 & 8 for extra mode options.
In Arduplane I can only find one, CH8 is there a hidden option to use other channels as well like in Arducopter.
If yes, were are they hidden
If not could they be added.
I use a rotary 6 way switch for mode selection but have a toggle switch dedicated to RTL, it would be nice if I could do this in Arduplane as well.
