Great that you tell me what is working, when I ask for something that is not working 😄
As said, I'm very familar with the possibilities what I can do and how. What I can't do at the moment is setting up an upcoming enemy, that is only listed as CM when it pops up from late activation.
But statement was clear, it's not a bug, it's a feature. I don't have to like this answer to accept it.
