Since BIAB doesn't support 6/8 time natively, you have two different choices.

The first is to use a Waltz style and then use two 3/4 bars to represent one 6/8 measure. You obviously need to adjust the tempo accordingly and your notation will not look correct (if you need the notation). But it should generally sound fine (depending upon the style).

The second (and generally preferred) option is to select a swing style (or one labeled as 12_8). It's not really 12/8, but it is implemented as tripletized 8th notes per beat. So for this song, you would have to use each beat for each set of triplets. So unlike the 3/4 method, you would have two bars of your song represented by one measure (bar) in BIAB.

The second solution is great for 6/8 if chords only change on beat one or four(as you indicated it does).

The first solution is required if the chords change on beats 2, 3, 5, or 6.

Neither solution will give you proper notation, but both should sound fine.
