BiaB is first and foremost a song-generation software. The notation feature is a convenience they threw in long ago and have not updated in years.
A third party tool would likely be faster/better than the above suggestion, but would likely incur extra cost and also still require extra effort.
FWIW I enjoy reading creative work-arounds like QuipRosen posted. There's always a way to get 'er done!


I do not work here, but the benefits are still awesome
