Was looking at the last twitch video and saw the new feature being demonstrated. But I can't figure out how to turn on that mode. I don't see any control button on my player cards. Is it included yet and I just missed how to activate?

It's "hidden" under the edit player modal.

Thanks found it and looks like only in Sandbox mode.

Yea, it's a "beta" feature that will evolve over time as we get feedback and as Asger has time to add more depth to it.
