According to the video, it looks like the only way is to get BIAB to generate the whole song and then import the melody MIDI into Synth V. Then try and make lyrics to fit that melody.
I watched the video. It started off with the chords and structure of a song, then added the melody and lyrics. BIAB cannot make a song from a single melody line. It was never designed to do that. In fact, I don't know of any product that could successfully achieve that. Others may know more.

You could give a single note melody line to 5 different composers and ask them to put chords to the song. I guarantee you that you would get 5 completely different results.
