VST plugin insert in headphone mix

I am trying to record new vocal tracks on the MR816csx. What I would like to do is play the existing instrument tracks and then record a new vocal track, but use a VST plugin as an insert (Izotype Nectar) so the vocalist can hear the effect in realtime. Is this possible to do in Cubase 6 AI, or do I have to wait for my Cubase 7 DVD to come in an use control room features?

Just installed the full version of Cubase 7. This works perfectly now.
