Now that I'm out of office, I can propose it. I wish I had this during my third term.

Charter, Article VI, Section 1 Wrote:1. The Prime Minister will be the head of government and the leader of the Cabinet. They will be responsible for the overall coordination of executive activities, being a liaison between the government and the community, and protecting the Coalition. They hold ultimate authority over all executive activities, though they may be overruled by unanimous consent of all their subordinate Cabinet ministers.

Something like that.
