Chauvet Slimbank T18 USB 13ch Mode for Colorsource AV20

Hi, the console (running 3.1) currently has the above fixture in the library with 3, 5 and 9 channel modes available. Unfortunately it doesn't have the 13ch mode and that's the one the lights are set in and they are too high up to change efficiently. Could the 13ch Mode be added please?
