Feature Request: automatic tags for collection

mspices

I was thinking that it would be convenient if we could choose tags that get set automatically whenever an item is added to a collection.

For example, if I have the collection "Food", I could define the automatic tag "food".
If Food contains a subcollection "Vegetables", I could define the automatic tags "veggies", "greens".

Then, if I add an item to Vegetables, it would automatically pick up the tags: "food", "veggies", "greens"
