There is a command to do this in BIAB. I think it’s called Reduce Duration of Chords. Where it is depends on the version. Older versions had this in the Edit Menu. Now I think it’s in Song Form. This function affect the entire song.
If you have BIAB 2018, there are timebase adjustments you can make for double or half time to RealTracks and now RealDrums.
