Dimmer 2 - 2 switch config

hi, i am new to smarthings and need some help with the code for the dimmer 2. I have brought 4 dimmer 2 modules and would like to install them behind the switch. The switch i have chosen is the schneider push button with centre off type, switch

I have installed the module for a one gang switch but i cannot setup if there are two gang switches. Is it possible to use the 1 dimmer module and appear like two devices within things?

Any help would be appreciated.

Thanks

Dale

ok, for some reason I assumed the module had two output! My mistake.

thanks
