Try placing a single MIDI note at the same place as your pickup note, on the Melody or Soloist track. Then set its velocity to 1 so it can't be heard. This may trick BIAB into behaving as if there was a pickup to a MIDI track and thus not playing the last of the countin IIRC.

If all else fails you could try Insert of one bar at the very beginning, then declare that bar to be an Intro using the first number box to the right of the Styles window, tell BIAB that the song starts on bar 2.

Then you'd have a countin, three silent beats and your pickup note.

Repeats (chorus) would then have to go from bar 2 to wherever.
