MC Control Room Question

[KeyplayerG]

Is there any way to program the faders of the MC to control 3 separate monitors in the control room? You get the one CR knob which works with the CR master knob in the DAW. But Nuendo allows for multiple monitors that can be balanced and run individually from the CR controls.

I would like to map those controls to 3 faders in the MC (1. Surround 5.1, 2. Large Stereo Monitors & 3. Cube Stereo Monitors). The only thing I've figured out is how to map the faders to the stereo out busses. But that will actually change the volume of the mix. I DON'T want to do that. I just want to control the listening volume like the CR knob. Is there any way to do that?
