Trying to do a multi surface setup

So I'm having a little difficulty figuring something out here.

I have a novation remote sl (mk1) I have it all set up nice and neat. All the mapping is working swimmingly.

I'm using sonar platinum.

I also have a Korg nanokontrol2.

Here is what I'm trying to accomplish here:

I want to use the remote sl the same way it is now. I have it set up as a generic surface. And I manually mapped everything with the template editor and the generic surface assignment window.

I want the Korg to control the busses and the master volume and maybe the metronome and preview.

How do I set this up? If I set up another generic surface, the options I want to control aren't listed.

This may be more advanced than my feeble mind can handle.

I would look at using ACT. I haven't tried two Generic surfaces together but I do run several ACT surfaces in tandem with a Generic Surface.
 
I actually use ACT and the generic surface at the same time on the same unit. I use ACT for knob, button and fader control with my ZED-R16 and the generic surface for transport control.
 
I have a video on my youtube page that shows how to setup ACT devices.
