I always move my tracks to my DAW where I can easily grab a kick or snare hit, copy and paste it to where I want to get what I need.

I find that method so much easier and quicker than trying to figure out how to get the software to do what I want in BB.

I have also added midi tracks and synths to the project and played the part into the song and used volume envelopes to do the edit as needed. With proper EQ, no one even notices that it is a different kick, snare, bass, or piano in that specific measure or two.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
