It's been requested since the original Move, and has never been implemented.  I wouldn't count on it coming in the future.

Yeah I figured as much - I just know that they’re releasing the new web app on May 7th and was curious if they’re going to add firmware functionality to anything. I feel like the hardware is plenty capable for setting up with the ARC for surround sound… my wife would LOVE not having cords anywhere with the ability to pick a couple of speakers up and achieve surround sound while not having them dedicated 100% of the time…

Sigh...

From what I understand, the new ‘app’ on May 7 is only a UI change, and has nothing to do with changes in functionality.
