Adding your call sign the data stream

Hello to the group,

I 'm not sure if this question been ask, but I will give it a shot.

Is it possible to add your call sign in app_rpt data stream when transmission occurs? Reason could be for IDing on digital systems like P25, D-Star or any other new to come digital systems.

Another thought, is the Archive of the mailing available? Would like to search or read up on the list about how to stop node connections and disconnections of announcement.
