Can I make styles from my audio clips I play into a tune?

I set up my drum machine last night to play a pattern and recorded like 2 million measures of it. Funny thing was that in order to make the metronome in RB match the clock of the drum machine I had to set RB at 126 and the Roland at 124. It stayed in sync for maybe 48-50 measures and then one of them drifted, but I can't tell which one.

Can I save that drum track out as a WAV and use it for a drum style later? I know I can always import that WAV as track one and go from there, but that seems like kind of cheating. The drum machine doesn't sound as good as the RB Drums overall, but I can't find anything close to what I need for this particular song in RB.
