Select specific users for which to auto-lock the machine

I am aware of the 'Selective Lock on Disconnect' plugin, and would suggest that this feature be added to it. I would like to be able to specify which users on the computers will have the computers auto-lock, otherwise do nothing. 

For example, I have a user called 'supportadmin.'  In Control's interface, I specify that I want a specific machine to Auto Lock on Disconnect, then additionally add the username(s) that it applies to.  I will add 'supportadmin' to that field.  If support admin is logged on and the session is disconnect, it locks the computer.  If any other user is logged in and the session is disconnected, it does not lock the computer. 

This will be useful for when techs forget to log out, and does not hinder any other logged on user.
