Ok, I didn't get that. I thought the workaround via the setlist would be already available and there could be an additional feature to reset the croping for all files. *Sometimes I should read the posts more carefully.*
Your description above seems for me like a reasonable procedure. Additionally your solution is much better than my first idea of resetting the complete database by default. Your proposal allows a specific selection of the files the change will be applied to. I like that a lot.
I would be happy to have such a feature.

Kind regards,
