Sounds like you may not be trying to use the thing in the right fashion. B substyles are certainly different from A substyles in most cases. This may not be the case with certain RealTracks, however.

Look up Part Markers and how they force not only the stylechange, but a Drum fill in the previous bar. Inserting a Part Marker of the same color as the one previous will force a Drum Fill without changing to the other substyle, often useful.
