Karma and Groups

[Draig]

I'm very new to forum set up so I apologize if this is obvious. I had a browse round the various karma mods but couldn't find an answer to this question.

Is there currently a karma mod that will take into account groups on the forum, so that a user cannot award karma to a user in the same group?

For example three groups, 1, 2 and 3.

I want it so that people in group 1 can only award karma to groups 2 and 3. 

Many thanks!
