Making zone passive or hidden when not in use

I have a Zone that’s on the other side of the country and is rarely visited.

I still want this zone to be used as a location when I’m there. However as it’s on the other side of the country, I want to hide it when not in use to reduce the scale of my map.

Is it possible to set up an automation to do this?

Wouldn’t that be done with the passive option from the zone configuration?

As far as I’m aware, when a zone is set to passive it will never show on the map.

It is only used for automation etc.

Can I use automation to set the zone to passive when no one is in it?
