Zone map should give better feedback

For Mutant Year Zero Road To Eden, it would be good if the zone map gave some feedback on which zones are cleare, and what the max level of enemies are.

Once a zone is cleared, it would be great if there was something on the zone map to denote that. And once the party has entered a zone and spotted all of the enemies, it would be great if the zone map denoted the highest level enemies left.
