P: Print to respective folders from multiple collections inside a collection set

This would be a very useful feature. If a collection set is created with multiple collections inside, it should be possible to print those collections to folders with the same name of each collection

eg:

collection set "Wedding"

     collection "Bride"

     collection "Groom"

     collection "Guests"

When printing all photos from the collection set, three folders should be created, each one with the contents of each collection
