I am setting up a situation where when the blue force captures a red force port, a blue force Supply Point A is established the next turn in said port (Event Activated).

Supply Point A has an initial value of X.
I want to over time increase the value of the Supply Point A.
My question is can I simply create a new event (referencing the old activated event) that is the same as the event that created Supply Point A and just give it a new value (Y)?
Or, do I need to zero out Supply Point A with one event; and, create a new event establishing Supply Point B that has the new value (Y)?
Does the new supply value automatically override the old value? Or, do the supply values stack (add to each other)?
Thank you,
Mark
