You'll have to first load the patches into A or B and then store the bank to ROM banks. The banks beginning from C are ROM banks and need to be burned so choose wisely what banks you want there because EEPROM's don't have unlimited erease/write times (usually about one million erease/writes but you never know what might happen).

Edit: Just store current A and B banks to a MIDI file and reload them after you've burned the ROM banks you want.
