Sending CC and NRPN at the same time

So I read:

That would be for any device that receive NRPN? So it will take 4 CC message, but then I will be able to control all NRPN by selecting different settings in the CC control page? Or I have to use 4 cc parameter for each NRPN setting I want to change?

Anyway - will try that tomorrow and figure it all out.
