Example:  I have created a collection (station) called Baroque Classical Music.  It plays various Baroque artists chosen by Pandora... but I want to "add" different artists/composers who do not appear in this collection... Is it possible to add new artists to an existing station (collection)???  When I try to add a new artist, it creates an entire new station, and I end up with 2 collections playing Baroque music... I would like all of the Baroque music to be in one collection... I used to be able to do this, but that feature has disappeared...  Thanks for your ideas... ... View more
