FR: way to make AI turrets fire at particular point on ship. Subsystem flag?

AI turrets (not sure about primary/secondary weapons) seem to be targeting the LOD0 mesh's 0,0,0 point/pivot point

This is where the model centre (0,0,0) is located

The model centre is placed there for specific ground vehicle-based script reasons but I can see this being an issue with oddly-shaped ships where the model centre doesn't correspond to the ship's hull.

One possible solution is to have a subsystem flag which has AI turret fire target it as a priority until it is destroyed. Also good for showing "targeted" attacks, Wrath of Khan-style against the Enterprise.
