Automatic modification date in syntax comments using Dreamweaver

Can I set Dreamweaver to automatically add some comment paragraph on top of the script, so that every time I save the files, a last modify date/time is added to the comment?

example

Software Name
file.php
Last changed: DATE_HERE - TIME_HERE

I’m doing this manually, but I want it to be automatic.

Thanks

If you were using something like Subversion, it can do that.
