The only way I have found is:
In Prefs set to Hi Hat
In RealDrums Prefs disable RealDrums
Turn Midi Drums up
Record Audio > Start of Song
Now you will have a Hi-Hat count-in on the audio track
Audio Edit to cut out anything on bar 1+
RealDrums Prefs enable RealDrums
You can also drag export a midi drum track
File > Import Soloist from MIDI file
Select the exported drum track
Choose ch 10 and import 2 bars
Midi Button > Midi Channels set Soloist to 10
how you change the patch to drums you can work out.
