The way the chords are voiced in BIAB is determined by the options in stylemaker where each pattern can be assigned different voice leading options.

'Smooth voice leading' will give the fewest note changes from the previous chord in the progression which will often give an inverted voicing.

The 'Transpose' option will keep the order of the notes the same for the next chord so that C E G Bb (C7 voiced as root 3rd 5th 7th ) will become F A C Eb if the next chord is F7.

'Riff voicing' will never transpose the notes of the chord and is often used as a special voicing over a particular chord type which you can also assign.

Otherwise inversions will always be attainable with an alternative bass note C7/Bb for example although as the previous poster says, the exact order of the notes above the bass root will ultimately be decided by how they appear in the pattern notation.

Hope this helps clarify things for you.
