Which trxn for Support staff to terminate users in a Load Balance system

We have trxn sm04, but it will only provide users that are logged into the system that you have been sent to in a load balance environment.

I was also considering al08, but that does not allow support staff to terminate users.

Is there another trxn?

Please advise, we want to determine a strategy for the support staff before we roll out load balancing to all SAP users
