Create-stems-from-selected-realdrums-stereo-track.zip
You can manually create up your Band In A Box RealDrums how you want them and convert to multitrack stems (if available).
Set Reaper to the tempo of the RealDrums you are dropping in then change Reaper's tempo to the Biab project tempo, or right click > Item Properties > Playback rate > "Set" to RealDrum tempo.
I hope the shots, holds and pushes have been added to the stems for 2024.

Below I have loaded the source RealDrums file wma, wav, m4a or aiff then copy the section to the top track.
I select the top stereo track and run the script to get the same sections as the stereo track.
