queueAction

Sonos players support queue actions to determine how to load content into the queue. Set queue actions in the loadFavorite and loadPlaylist commands.

Set the queueAction to one of the values below:

Queue Action	Functionality when enabled
`APPEND`	Append the new content to the end of the shared queue. If the playMode is `shuffle`, Sonos shuffles the new content in with the unplayed content. This is the default behavior.
`INSERT`	Append the new content to the end of the shared queue. Sonos moves the playback head to the first enqueued content.
`INSERT_NEXT`	Insert the new content into the queue so that they play after the content Sonos is currently playing. If the playMode is `shuffle`, Sonos will play only the first added track next.
`REPLACE`	Replace all the tracks in the shared queue with the new tracks.
