[Question] Any way to sync map progress?

Hey :).
I figured out the webmap is using the fog.png to determine what progress has been made in discovering the map.

Is there any way to sync this progress with the client(s) / user(s) progress?

My friends and I use the ServerSideMap already, so we're all synced up so to speak.

It would be nice if there was a way to sync the progress, so the webmap doesn't look so empty..
Is there any way to sync one of the players/users progress with the fog.png in some way? 😄
