I was doing the exact same thing yesterday except it's Blue Trane and have the same problem. The best way is to open that song in Real Band as a Biab song and copy/paste what you need and you can adjust the gain there too. The reason for that is the chord grid is already done. One useful trick is after you've generated the basic song go into the chord grid and make a shot every bar for as many bars as you have patience for then generate another RD track. All you need is the raw material to cut/paste what you want. You can keep the tune in RB if that works for you but if you simply have to keep it in Biab import the corrected drum track into Biab's audio track and mute the drum part. The problem with that of course is if later you want to make any change to the tune in Biab that drum audio part is fixed and you'll have to redo it in RB so make correcting the drum shots the last thing you do before finalizing it.
