Cubase 5 - Fader Controls and Waves Rewire

Mac OS 10.7.3
Presonus Studio Live 16.4.2 - Firmware version 1.50a - Build: 184
Cubase 5.5.3. Build 651

Is there a way to control Cubase Faders with my Presonus?? I´ve been searching for an answer but I had no luck.

I also have Waves Rewire installed. I can only insert the main output channels and return them to 2 input channels. ¿Is there a way to insert any of the 16 input channels that I´m missing?

Thank You
