please add the URL to the downloaded file's metadata in Get Info window (same as Safari does)

when one uses Safari to download a file, it inserts the URL into the metadata of the downloaded file (in macOS Finder, execute the Get Info command from the File menu, then click 'More Info', and see the 'where from' field within). Currently when using 4K Video Downloaded it efficiently downloads files but it does not attach any metadata to them, so that at a later point in time it's impossible to tell where the file came from.

I think this functionality would be very useful to many people -- thanks for considering it.
