Guys, IMO this is exactly what Scaler does so well. BIAB, by way of its Styles, dictate the specific voicing (including extensions) implied by the chord/scale. This is the algorithm and as indicated, it is less than accurate. Scaler, on the other hand, will harmonize the chord/scale exactly, per instruction by the user, though triads, sevenths, ninths, 11ths and 13ths. Each chord voicing can be specifically set and played. Scaler creates the midi notes and then it is up to the user to direct the midi to the different instruments in the band (by the way, directing the midi to the band is something BIAB is the master)

Having said that, I have to concede that this apparent limitation by BIAB does not mean much to the average user. The product has done quite well for itself and its users for decades just as it is. But yes, a few would be a bit happier if a more intelligent fix was available.
