Help track percussion

[ektor_s900]

Hi, I am trying to create a Colombian style here in psr-s910, but I have the problem that it has another percussion channel different to the one that uses "RHY1 - RHY2" and I tried to create it in PRH2, you can not. Well, I have 2 concerns:
1. Can you do this and how?
2. Yamaha in one of its styles, yes! Attached musical style file 36. Hard Rock of the PSR-510
Thank you I hope your comments and help and among those who can.
