There may be a control somewhere in BIAB to do what you want. It's been years since I've seen it (if it indeed exists). Try unchecking "Vary style in middle choruses". If your song can fit in the BIAB limit then one long track will stay in substyle a. For instance a 32 bar tune can be written out 4 times with no change in style.
Check out "substyles" in the help-index menu.
