Continued Exploration

Hello, what I'm wondering is if it's possible to auto-explore even after the fog of war is gone. I ask because during late game, I love to have naval units patrol the oceans for various reasons such as reconnaissance, easier mobility in times of war, and even for the simple joy of just watching them move. Sorry if this is in the wrong place, but can anyone suggest a mod or even how I would set it up in the SDK? I have very little experience coding and I don't wanna mess anything up...
