I have both Cubase7.5 and Nuendo6.
The panning options are identical.
In the preferences under VST drop down menu ,you have 3 default stereo panning modes.
Stereo Dual Panner (Remote Control Devices only)
Stereo Combined Panner
Stereo Balance Panner
So it should be there for you in Cubase.
I don’t really understand the “remote control devices only” option, and of course there is no mention of it in the manual.
