To intermix 4/4 and 3/4 in BIAB, you have to tell BIAB the song is 4/4 and have the first measure be 4/4. What you can do is make that first measure a dummy measure with C. for no sound, and begin the real song in measure 2. In measure 2, use F5 to select 3 beats per measure. Then proceed normally.
