Based on a prior post by Fergus, without looking at GC documentation, I think maybe all it takes to substitute a Dragon for a C (Applet's Caliph) in a preset is (using Auto Alfaerie PGN set):

...C D c d...
Where D stands for Dragon and d stands for dragon, in the Auto Alfaerie PGN set.
Leaving out some stuff (with ...), but I hope Fergus (and H.G.) get my drift.
