After looking at the code, changing to the foreach was not going to work to fix the issue for every case. A fringe example would be 2 EngineStates share the same System that depends on another System that is switched out with each state. Simply changing the For loop would not address this use case. Adding signals to the Engine addresses every case I could think of and is a useful feature as well. Imho at least.

I provided default values for the priority variables in the function parameters to maintain backwards compatibility.
