TimeTrex Time and Attendance

Is there a way to add a message to pop up when people log out?
Like, don't forget to clean up before you leave... etc...

Paid editions of TimeTrex have the ability to show messages before/after punches to employees, but its not a set message that always appears, instead they can read messages sent through TimeTrex, or get notifications of things like exceptions or prompts if they are punching outside their schedule.
