Forwarding requests after huntgroups processing

So far I figured out how to use the 'forward' config setting to forward 
incoming requests to multiple radius servers. This is a really nice 
feature I haven't found with other radius server implementations. Well, 
I actually only managed to forward the requests to localhost targets 
since the forward socket always binds to localhost, even if I specify 
the correct source-ip in config. But I guess that can be solved rather 
easily.

My question is if it is possible to forward requests *after* the 
huntgroups got applied. I'd like to use the rewrite engine in order to 
manipulate the requests and send them on to a list of radius servers.

I'd appreciate any hints on how to achieve that,

thanks,
