rlm_sql: more xlat?

Hi all, my requirements state that if home server sends policy then freeradius proxy should attach it to the string for rate limit and send RATE_POLICY back to RAS. Rates are determined by radgroupcheck and radgroupreply tables lookup. So far I hacked that in rlm_sql.c, simple strcat of Value and hardcoded attribute. Ideally, I'd be able to enter 256K_%{ERX-Ingress-Policy-Name} as Value field of radgroupreply table. This means database values should be xlat-ed too, not only parameters. So, interested in such a patch? Or, is there another way to do this? Regards...
