Proxy using rlm_perl

Hi good people, I have a question in regards to proxying my Auth & Accounting logs but not for all. I can use proxy module but looks like that only works for realm but I wanted to proxy only some of the user's record. I am already using rlm_perl module for custom stuff. Is there anyway I can add the proxy thing in my perl script? Thank you. -- Regards, Jehanzaib
