To protect my files I only have the option to protect the whole library.

That's not that what I want.

I want to add/drop tracks into/from a crate. But I want to protect my files because I don't want that Serato updates my files (with e.g. analyze info, BPM or whatever).

With the current ONE option it is not possible. So please make two options:
- protect crates
- protect files

Thanks
