You can program them to what ever you want, AH doesn't limit you there.
You will have to reset the switch before that function will operate again.
An example is I have one of the toggles on the throttle set for engine start with the switch being move forward to start engines (E). After the engine has started I move the switch back so that if I need to kill, or restart the engine I can just flip the switch forward again. Hope that makes it a little clearer.
