That's not a bad idea, though the exact format will be an issue, and you could achieve this through your file manager and a renaming program, but that's understandably more effort. Maybe I can add y/m/d h/m/s variables that you can use as desired. I'm slogging through technical work on my addons right now and don't expect to work on new features for some time still though.
