Extra Fields - File type

[TheAner]

Hi, I was curious if it's possible to add support for file type extra fields.
After getting better with 3D printing, I'm getting better with calibrating profiles for filaments and wanted to store/backup them and mark (other than the boolean type field "is calibrated") filaments that I have calibrated (sometimes I use/clone profiles from similar brand + filament type when I don't have the time and it works, but not perfectly).
I also want to share Cura filament profiles with my girlfriend.
I know that different batches of filament could have slight differences in additives and, therefore, different calibrations.
However, it would still be nice to store, for example, product specifications, Excel files, or pictures.

Ofc there would be need to have upload/download button in spoolman panel.
