Atmos mixing with Ambidecoder AND speakers

I am trying to set up in the studio Atmos mixing with the ability to monitor through 5.1 speakers and also through the Ambidecoder.
I can set up and make it work each of the monitoring option by itself, but it seam that each one (speaker, and headphones) is require to be the default monitors, and therefore I can’t figure out away to have both with switching between them.
Am I missing anything?

Never mind,
