Ability to view zoneSuggestion

Hey!

When players are in a zone (usually for an event), I would LOVE a way for them to see the boundries of the zone. As of now, the moment they step out of the zone, boom and death. 

One user suggested me building physical walls around the zone but it will take FOREVER because they are large zones. Plus numerous zones, it's just not ideal. 

It would be great for an option to make the zone walls shimmer/glow some way to distinguish if a player is nearing the zone.

Does this exist already? If not, would it be possible to add that option?

Much Thanks!

Yes, exactly that! Thank you!
