Here's a great suggestion from -steve- in the Cubase forum.

When I tried this ages ago with Cubase it was using a held piano style but was played in inversions and Cubase didn't pick up the correct chords now there are a lot of MidiSuperTracks with Held I tried it with Piano Held Acoustic 3002 it picked up the correct chords though they were just simple.
So try it out with some more complex chords with the different MidiSuperTracks and see how you go with it.

So just drag the track in and select it
Project > Chord Track > Create Chord Symbols
