Real Drums...no. But you can save midi drums to separate tracks. Via the Midi button (or F6), Export song as midi file (several previous BBW versions do this), in the "Choose destination for Standard Midi file" dialog, select "Drums on separate tracks" in the save as midi file type pull-down.

A lot depends on the style chosen and drum instruments involved. But then at least in a separate DAW (SONAR, etc.), you can than use different drum kits and and or drum instruments there. Even without saving as separate tracks, what drum voices are played can be managed with a drum mapper in a DAW or drum VST. But, the separate tracks provides a lot of flexibility. Often, I use both BBW midi single track drums and separate track drums for a given song. Also, this is a way to augment real drums with midi to add percussive sounds not included in the real drums style.

Hope this is of use,
