Multiple Active Game Views for Multiplayer Testing

A while back I saw a demo of a feature which allowed multiple game views to be launched during playback for multiplayer testing. I'm now testing multiplayer, and this would be a huge time saver -- does anyone know if this capability has been exposed anywhere, and if so, how to enable it?

*Update -- the feature is called Multiplayer Play Mode (Games Focus: Creating and operating connected games with multiplayer networking | Unity Blog).

 

Use ParrelSync.

Unity is working on something like that but to my knowledge this isn‘t in any public version yet.
