Ability to batch edit tags at a Folder Level

Example directory structure:
label / artist / album /music.mp3

In folder view it would be nice to open the ‘label’ folder, select all the artist folders and add them all to a label-specific collection.

If each label has a lot of artists each and you don’t know who belongs where without the directory structure it’s time consuming.

This feature seems simple to implement, but I’m no expert.

I thought of this for large movie packs actually, but the label pack seemed easier to understand when typing. My movie scenario is
Person A Movie Collection/Individual Movie Folders/Individual Movie File
Person B Movie Collection/Individual Movie Folders/Individual Movie File
In this case it would be nice to be able to select all the individual movie folders under Person A and add them to a Person A Collection, as opposed to the current need to select the files.
