I'm not sure I understand the question, but I'll try...

What your piano-roll image shows along the bottom is a "walking bass" line, so here I think bass is the boss and that's not uncommon.

BiaB can usually be persuaded to do that by putting the slash option into the chords, though frustratingly BiaB does not honour the slash note if it's the root of the chord, so C/C and Am/A do not guarantee C and A respectively as the bass note

Writing the chords as you have in the piano-roill may be the best you can do.

You could try clicking on the Bass track description in the mixer, then Track Settings, then choose a "simple arrangement" option.

You could, of course, set the Bass track to MIDI, edit it directly to get the notes you want and freeze it.
