How to Setup NanoKontrol2 as Generic remote control?

Hi, I’ve a question:
My control is a Korg NanoKontrol2 and I connected it to Cubase by Mackie Control, so in this way all the faders work for automation in mixer, but i don’t need so much faders.
I would like the last two for the Out and Metronome’s volume control, and 2 other fader for control Modulation and Expression (CC1 and CC11).
All the others controls are perfect as Mackie Control does, but I need a reconfiguration for the faders.

Can someone help me?!
