"Roaming only" sector property

[NGX]

It would be neat with a sector property flag that prevents monsters from going to their attack states.

There should be many subtle uses for it, but as an example let's say there's a Cyberdemon in a rectangle shaped sector with a pillar in the middle of it, like so:

------------------------
Cybie
----------( )---------


By separating small areas inside the rectangle and in the vicinity of the pillar, we could prevent the Cyber from attempting to attack the player only to have his rockets blocked by the pillar.

But the actual use I would like to use such a feature with is to have monsters roam in certain sections of a map but not necessarily attack from those places, like some kind of an alternative to "monster path nodes".

Added. Of course it needs to be said that this cannot deal with monsters that use special attack logic, like some of Hexen's and Heretic's.
