State category in message

Hello again, I'm thinking it would be really nice if userpoint messages, mentioned the category that the transaction involved.
Currently I'm using Points to track a couple different things. And the messages are always generic "User earned X points, total is now X")

Thing is the total given is for the proper category, but doesn't say which one.

Where in the code is this handled? I imagine if it's pulling the total from the proper category, pulling the name should be simple.
