You could mute all other chord instruments at that point, and let the bass alone play.

You can adjust the lowest note the bass will play, to try to avoid the register jumping. Options, Preferences, Arrange, Lowest bass note. Dropping the lowest possible note might encourage BIAB to choose the lower octave. Experiment. Manually editing the register of that note is the only other option I know.

Yes, I would love to see support for the chord root and slash root on the same note, for precise control of moving bass lines like in this case.
