Plexamp should be able to cast music to each network speaker independtly

It would be great if plexamp can cast music to each network speaker independently. The feature request is already implemented Sonos or DsAudio app.

I would like to see if plexamp is able to cast a song A to a network speaker X, a list of songs to a network speaker Y. This is similar to Sonos or DSaudio app that can selected music to a selected network speaker, thus each network speakers or rooms can have different playing songs simultaneously.
