would it be posible to asign one joystick axe to two plane controls? servotabs on 109

I think he wants to assign elevators and elevator trim on the same axis...I don't think it would be a good idea, trim has to be independent from the elevators, I don't see how the plane would know exactly know what trim you need at any moment for what you, as a pilot, want to achieve.
