I am sorry it is not clear what you are asking for.
if you are asking if you can assign a USER at the probe level instead of when it gets to the UIM interface the answer to this is no.
Alarm message do not have the ability to store an assigned user.
Users are stored at the primary hub and database levels and probes do not know about these users.
The fields do not actually get added to the alarm message until the reach the primary to be able to assign a user.
if you are referring to something else please provide more details and examples so we can try and help.
