MCU Pro Master Fader to Control Room

Anybody know if there is a way to map the master fader on a Mackie Control Universal Pro to the Control Room main volume instead of the Stereo Out channel? I never change the main output from 0dB for mixdown purposes, but I would like to use that fader to control monitor volume. Since I use Control Room quite a bit, I think that would be the ideal setup. I’ve never been able to find a way to do this, but maybe there is something new in Cubase Pro 8. Any ideas?

+1 that would be fantastic
