I reported the this issue with RealBand in the beta testing forum.
You could run 2 instances of Biab,
save the first and second half the chord sheet in MuseScore,
load one xml into the first instance of Biab and the second half into the other,
you can then highlight the bars in each instance of Biab and drag export them into Tracktion so the second one will include the ending.

EDIT: I just hope they will give the plugin more than 255 bars also.
