I'm not sure how to word the question, but here's the problem.

I'm using chord system in Gm, thus:

Gm, Eb, Bb, F

This is for 8 bars, but on the 7th bar of Bb, I want one of the notes of the Bb a little higher.

EG
There are 3 ways to play a Bb chord using these notes and they sound lower or higher depending on what notes are being played.

D, F, Bb
F, Bb, D
Bb, D, F

Notice how the notes are still in Bb but get progressively higher, the D in the first set being the lowest and the F in the 3rd set being the highest, this is what I'm looking for in playing a Bb on the 7th bar playing the Bb as F, Bb, D, D being the as the highest note, as it stand now, the chotes are the same, a Bb is the same regardless where it's positioned, I know if I use Bb/D it would play the D as the bass note, but how do I get BIAB to play the D as the high note? In chordPulse I can enter Bb+D and it would play the D an octave higher.
