SSE Confine NPCs to fight within an Area

[Deleted56253002User]

Is there a way to prevent NPCs from moving out of an area when in combat? I am modding forts now, and I want the archers to stay put inside their defensive walls and towers, and not for them move out of their forts where they'll be at a disadvantage.

 

I am thinking about using AI packages and Idle markers as a first step, any ideas?

One way to do it is to:

Make a 'Package' to force the npc to use only "Preferred Path", then in the part of the cell where the npc will be, "Preferred Path" the NavMesh.

The "Preferred Path" NavMesh must be completely cut off from any other "Preferred Path" NavMesh, also be sure that there isn't any "Preferred Path" beneath it, like in a lower floor of the tower.
