Cubase AI5 Mixer

Hey guys,

Just a quick question I am running my EZdrummer plugin through my cubase ai5 and made it into a multi-channel mix i.e kick,snare,toms etc on seperate channels instead of just using one channel. when i open the mixer i want to expand it to extended mixer options. is this feature available on this version of cubase as I cant seem to find the option to do this?
