Can Midi Tracks be volume/mute controlled by a VCA Master?

Seems like you can't control the fader volume and Mute function over several Midi Tracks by grouping them into a Master VCA.

Moreover, it seems that when grouping a Midi Track with a different type of track(Audio or Aux Track) The fader and the Mute button wont react on the Midi track/s that are in the group.
Only the Aux and Audio tracks respond to Fader and Mute command within the group...

Any input on this? Its a real problem for what i am trying to do, and nowhere in the documentation, or on the web, could i find a mention of this abnormal behavior of Midi Tracks...

Thanks!
