I would need to know what style you are using to see how it sounds in BIAB. For example, in Celtjig.sty, BIAB handles 6/8 in 4/4. Each measure is two bars of 6/8; in other words, every quarter note is a triplet and two beats of 4/4 is 6 beats in 12/8.

Assuming your style is like that, the technique is to go to the first bar, press F5, and enter 2 for beats per measure. Then go to bar 2, press F5, and enter 4 (which restores the 'normal' time). Do something similar at the ending bar.
