Tracking time for Project

Thanks, I've read these but I'm afraid the functionality I'm looking for is more along the lines of the old Autocad tracking of total modified time per document, which functionality does not appear in SolidWorks.  I can understand why, as it's probably pretty meaningless since you can have parts open for the assembly without necessarily "editing" the parts.  But for me, it would probably get close enough.

Some sort of "editing tracking" would be very helpful for SW to add in, however,.... hint, hint; Development Team...
