Level up sound on reputation rank up.

[DonnieDice]

Currently trying to figure out how to add sound to reputation rank up. I can't seem to find a RegisterEvent thats related to reputation rank ups, similar to PLAYER_LEVEL_UP. I think in wow when you rank up reputation there is some sound file that plays, and an green level up animation that happens on your character. I am trying to change the sound that plays when this event takes place.
