The easiest way to handle this is with Bar Settings (F5). On the bar to change drum kits, press the F5 key. You will see a RealDrums button that will bring up the RD dialog. Use the F5 anywhere you like throughout the song. As long as the drum kit you choose has those options (snare/highhat and snare/ride), it will work.

Depending on which multistyle chosen, one of those may work for you too. You just have to audition them and see.

If you will be doing this in a lot of songs, creating your own multistyle is probably the way to go. I don't recommend trying this at this point but keep it in mind if you are using the same drum combinations in a lot of songs.

Also, put questions like this on the BIAB forum. It will get more attention there.
