You can either manually program an intro, verse, chorus,bridge or outro manually and individually as I detailed above or if you prefer, you can program your own custom MultiStyle with up to 24 different part markers and alter Styles in that manner.

From the BIAB manual:

Band-in-a-Box MultiStyles are styles that can have up to 24 Substyles; original Band-in-a-Box styles had two Substyles, "a" and "b." Band-in-a-Box MultiStyles typically have four Substyles, but may have up to twenty-four, selected by using part markers "a" through "x."

You can easily make your own MultiStyles, either from scratch, or combining parts from existing styles to make a MultiStyle. For example, if you have 10 favorite Country styles, you can quickly make a single MultiStyle that has 20 Substyles available within the same song.
