So do you make it up first in BIAB then put it in your DAW or do you just use it straight from BIAB ?
If you export the tracks to your DAW you can just edit it in that, open the RealDrum m4a/aiff file from the Drums folder and you will find some hits (shots n holds) at the end of the file then you can copy and paste.
Try and put a blue or green part marker on that bar.
