This is kind of a long shot here.. but I'm wondering if there's a way to assign the Parking Brake dial to an axis.
I just got a Thrustmaster TWCS throttle and there is a useless-looking knob under the pinky that I think might work perfectly for this.
To clarify, I know the button assignment for that dial is toggle brakes max. What I want to do is to simulate the rotation of the dial, as if I am using my mousewheel on it.
