Nashville Notation is my favorite way of displaying chords in BiaB.

The problem is, BiaB doesn't allow me to choose whether to display a sharp chord or a flat chord on the chord sheet for the same chord.

The 4# chord is displayed as a sharp chord, which is exactly what I want.

Here comes the problem. The 2b chord is displayed as a flat chord, and I don't want this. I tried to re-type "1#" in the slot, which is essentially the same chord, but after I hit enter, the chord automatically changes back to 2b. Tried this on the 3bm, 6b chords, got the same results.
What should I do?

I right clicked on the Part Markers, added some "Bar Based Section Text". Although I changed my chord font to Arial font, these section labels are still displayed in the default Big Band font, which looks very unprofessional.
So, in BiaB, is there a way to change "Bar Based Section Text" to Arial font?
