Proxy accounting

HI This is slightly related to my last question I have some realms that I am running a proxy to another server for auth and accounting. Is there a way with accounting to proxy but also have a copy of the records on the local SQL server (as though they where not proxied) as well as sending them to the remote server. I don't ned this for auth on the affected realms - but it would be useful to have the session & accounting data local if we could - as it helps us debut issues for customers without having to use their portals ? if you can provide a pointer I'd appreciate it Richard
