It would be useful if there was a way to configure auto-generation of factory file names based on job properties. (Maybe other file types too)
For example, printer, filament profile, job name properties might be incorporated. However there are other 'properties' that might be useful. Date, custom text, etc. In fact no lack of properties you might use...
As for providing some sort of interface to manage this, the best analogy I can think of might be akin to a .mp3 file rename tool. Where you select artist, album, track etc. Something alone those lines.
Managing and organizing the files for 3d printing - especially amongst multiple printers - can be cumbersome. Whilst one might consider some kind of clever RDB approach to managing all this in the software, I think this is a simpler approach, which effectively keeps the problem in the user's domain but provides a means to make it a bit easier to manage files and even save a ton of typing.
I'll be surprised if this hasn't been requested before, but who knows? Hard to tell from search results I got.
