It is possible with MIDI but not with Real Instruments.

Using MIDI, you have two ways to do it, for static defined parts, I prefer writing them out or recording them as MIDI to the Melody and/or Soloist tracks. That way the parts won't change when the song is reloaded or when you hit Play again because BIAB will regenerate all the accompaniment parts slightly differently. Then use Rest Instruments command at bars where you don't want the accompaniment instruments but just the static part you entered.

Another method, still MIDI-based, is to edit the Style using the Style editor and place your own patterns in there. This can be more tedious to do, but may be better for certain situations where you wish to use those patterns in more than just one specified song.
