I don't think any of the RealDrums were recorded with solos or rolls but
you can open the RealDrums source file in Biab then copy and paste the section to another instance of Biab.
The PG Sforzando Drum kits could be the same kit the RealDrums were recorded on so you might be able to get the matching sound with a bit of tweaking ? Until they enable Playable RealDrums and maybe some more Sforzando kits to go with them.
Or use something like EZDrummer.
