The four city actions of Sacrifice, Banish, Start Inquistion, and Procession are useful abilities that give decent penalties for a small cost in money or population.  It would be nice if we could toggle them on/off instead of needing to remember to look through our cities every X turns to reactivate.

Proposal:  When we activate any of these four abilities, the ability should toggle on permanently instead of just running once.  In X-1 turns, one turn before the action would happen again, we get a notification (like when Mercenary contracts are about to expire), and we can choose to go to visit our city screen(s) to inactivate it again.  If we don't turn the ability off, it will auto-renew, costing us population or money, and continuing the benefit of the ability.
