<< I did eventually manage to get quite a decent bass track with the slash chord method, but it caused some weird sounds from the guitar track because that also is generating slash chords with the Eb and Bb bass. >>

To avoid these anomalies on other tracks in the future, Create your chord chart normally, generate the chord chart and freeze all the tracks except the Bass. Then edit the chord chart to contain the slash chords and generate the Bass track. The other tracks will not generate and the bass will follow the slash chords.
