Manipulate the TO user inside the LRT

Hi,

I am using the SBC 3820/3900 version 7.4 in order to translate national number in private number (force onnet routing).

For that i configured in the Local Policy, the multistage routing (lookup=multi) in order to change the R-URI number and i added a HMR to copy the R-URI user on the TO URI user (if not, the destination doesn't connect the call).

My problem is that i need t o implement the HMR (to copy the R-URI) on the In-manipulation of all the Session Agent (or Realm) for all the traffic toward  the SA. This configuration is working fine but this is not optimized solution (useless manipulation for some traffic, additional CPU used...)
