Currently, when an area is restricted to Zeus, the area extends vertically to infinity.
I suggest allowing the mission maker to change that height instead of being infinite to being a specific number(in a dome or rectangle shape)

This way, Zeus could airdrop units over restricted areas, this would be an incentive to using the paradrop option as opposed to instantly placing them in unrestricted areas and setting a waypoint.

And the same for edit only areas, mission makers should be able to restrict their height too.
