Update the metadata of all notes in a folder

[ltctceplrm]

Is your feature request related to a problem? Please describe.
I did a bulk import of movie entries before the actor field was added to MediaDB and would like to add it to my previously added notes, since there's around 1500 of them it would take me a lot of time to go into each note and click the update metadata button

Describe the solution you'd like
Ideally I'd like an option to right click a folder and select "Update all notes in folder"

Additional context
I know there's already #10 that got closed because it would put too much stress on the APIs and that's a very valid point but I think that having MediaDBdo an API request every 10-20 seconds (or maybe even longer) would be a good compromise
