Device and User Mode - Agent status

I have a customer that is using Device and User Mode. Freepbx version 2.210.62-6 Asterisk 1.8 We are having a time with some of the users forgetting that they logged in somewhere and logging in somewhere else. Probably a common complaint. Is there a way to create some type of report to show who is logged in where? Ideally I would love to be able to change the Name value on the Yealink T26 phones they are using to reflect the User that is logged into that phone.
Thanks for any ideas, suggestions
