Hello hoax23 (if in fact that is your real name )
You might want to take a look at my CadTempo software that was designed to log various cad (and other) programs.
At this time it does not have specific job naming as you describe but is more based on drawing names and depending on your directory structure it may provide what you are looking for. In other words if your files are set up on your hard drive like C:\Job Name\floor\meeting then all work within that folder (and subfolders) is easily accounted for and retrievable.
Forgot to mention that it is automatic, your employees do not need to do anything for logging to occur.
