Set phone volume from tizen watch app

Hi, I would like to make an app that allows for changing volume from a samsung watch when music is playing on the phone the watch is connected to. I can see that tizen.sound.setVolume allows setting the watch's MEDIA volume, among others, but that doesn't affect the phone volume. I am thinking it actually has to do with Media Controller, but I haven't found a way to do change volume through that.

Is there a way I can change the phone's volume from a tizen watch app?
