Audio balance setting for media player

Would it be possible to add a setting to adjust the audio balance between left and right channel in the built-in media player in Home Assistant?
Application example: A small amplifier with stereo speakers is connected to the Home Assistant. The left speaker is installed in room A, the right one in room B. Now I would like to hear music when there is movement in the respective room. Home Assistant is currently playing music in stereo mode in both rooms. However, I would like a setting such as Left: 100%, Right: 0%. If both are to play, then Left: 50%, Right: 50% etc.
Thanks in advance.
