This is my own breakthrough after listening to . I now know how to add people. All of my ICM builds so far have had stages, and each stage comes with a single costume that my agent puts on to perform that stage. Now I know I can add a roster of people, and I can have the right person work on the stage. Then I am able to have a second person review the stage.
The nerdy side of me wants to talk about finding a second degree of freedom.
