The way we model them, using stability derivatives, we don't need to as these things are wrapped up in the aero data itself. The coefficients we get will be roll_moment_due_to_aileron_deflection, pitch_moment_due_to_elevator_deflection, etc. and this data will include the effects of motion of the pertinent aerosurface - symmetrically deployed or not. Take the F-16, for example. The pilot roll command goes to the flaperons and the horizontal tail and is split up into left and right side commands. These commands are exactly symmetrical for the opposing sides, but of course they different in sign. If the left flaperon goes down 2 degrees, the right one goes up two degrees. There is a mechanical bias of between 1 to 2 degrees for the lateral surfaces, but I doubt you can see this in the visual model.
