proxy accounting to two other radius servers

[Bill Schoolfield]

I have a accounting only proxy in place to a single radius server. Works 
fine. I now need to proxy certain accounting packets to another server.

Both request types have the same realm but there is a unique suffix to 
the username portion.

I looked over the docs but I can't seem to figure out how to modify the 
configuration to do this.

Can someone point me in the right direction?
