If you open DrumGrooveNames.txt and search for: snare on beat 3 (in \bb or\bb\Data)
as all the grooves are listed in it.
They were going to have a beat finder in the drum picker where you just select the drum/cymbal on the beats you need then it will search and show a list of compatible drums. Like Tap2Find in EZDrummer but just a bar or 2 of beats and you have a checkbox for each drum on each beat, bb could then analyze this and search the DrumGrooveNames.txt and filter the drums in the pick that are comparable.

You can also download the midi file and create a loop, UserDrumTrack or RealDrums from it. http://www.realband.org/tutorial-utd.html
