Need help with N6/Artist MC set up

I am a Cubase user, looking into upgrading to Nuendo. I am now demoing Nuendo 6.0.7.
I have noticed in your screenshot, Fredo, that under the Eucon adapter Settings there is an option that I don’t have: “Mirror Main Mixer”. What is this and how can I get this option? This would be a game changer if it was what I think it is!!

My Avid Artist Mix system works flwlessly under both Cubase 7.5 and Nuendo 6.07 Demo. Under Settings, the Eucon adapter version shown is indeed 6.5.1.5 built Feb22 2013 (I noticed in your screenshot though that yours is 6.5.0).
