Mixer and few midi lanes

Short question.
Is it possible - if yes, how - to have the mixer view in C6 with only few (not all included in project) midi channels. They are collected in one group and I want to see only their view to navigate by mixing controller.

Have you come across the Hide button yet? More than I care to explain this late at night so have a look in the manual under Mixer (p.150) - Can Hide and View Sets are what you’re probably after.
