Steering wheel pedals (Rudder) with CH Yoke?

I have a G25 wheel and pedal setup and am curious how I can setup my pedals as rudder along with the yoke. Is this possible? I would think it should be, although it seemed I can only assign one axis for rudder. I'd like to have the gas pedal be right rudder and the clutch left rudder. When I was using a joystick before the yoke, all the pedals and buttons were active to be used in FSX. Once I installed the yoke, the G25 at present is not active in FSX.Thanks guys!Todd
