[Users] accounting of final replies

Hello all, i need to do additional accounting for final replies with the acc module, especially distinguish local from forwarded replies. We patched 0.9.5 for this functionality. We add a flag to the message, that is set by tm, and read from the acc module and then added to the log message. Is this possible in 1.2 with the extra accounting functions and pseudo variables? Or is the approach described above still prefered? I know that there exist the t_local_replied() function in tm, and it is perhaps with that possible to log a message in the config file with add_log_request(). But it would be nice if this information could be included in the normal accounting log message. Thanks, Henning
