I do it like Mario's second idea.

Open Realband
Right-click an audio track and choose Generate-Generate Realdrums

RB's Realdrum picker pops up

Look thru the list of Realdrums (not 'styles', Realdrums)
You get a different way to look at it.
You don't care about the style, as all you wants is the drums.

Note that in many RD's, on the right of the picker window is a small window labeled Variations .. this can add a lot of context (sidestick in 'A' or Snare, hihat or ride, etc)
You can still select A & B parts in the Chord window if you want some variation on the generation.

Just another way to skin a cat

Note that you can click Audition in the picker window
Click Audition; you'll hear that RD (with accompaniment, but you'll be able to audition that RD).
Understand that it Auditions at its default tempo, but it will adjust to your tempo once you click Generate.

I do not work here, but the benefits are still awesome
Make your sound your own!
