Yamaha DGX 660 Accompaniment Set up for Bass note?

how can I change the bass note on the yamaha dgx660. For example the music sheet shows the chord of C/E. What is the set up so it sounds like the E is the bass note? I had this on a very old Roland Synthesizer (E56). That feature was called ACC BASS REVOLV. It made quite a difference in the song.
