How do you upload saber fonts with the Diamond Controller

[Cashless]

I was hoping if someone could inform me on how to put custom sound fonts onto the diamond controller, such as this Kylo Ren Font:

I always have trouble trying to find and apply each sound into each category because the launcher doesn't seem to register the files, even when I tried the Old Republic Jedi SoundFont on the UltraSabers website it couldn't register it either.
I hope someone could help me out
