I have a question that may have an obvious answer that I have not figured out yet. I have a 2018 13" MacBook Pro, and what I want to do is have whatever is Desktop 2 when not using an external monitor automatically fill the extended portion of the desktop when hooking up to an external monitor.

It seems that when I set up Desktop 2 and then hook up my external monitor, it automatically makes the extended desktop now Desktop 3 (a new blank desktop). What I want is for those apps to just occupy the secondary screen. Is it possible?
