How to set an NPC to own a cell in CS?

[apachewarrior7]

So I have this old mage guy who owns a dwemer emporium that I built, but players can just steal the valuable items inside Scott-free. I looked at the initial cell creation menu and I didn't see any option to set the owner, but maybe I was missing something. Can anyone help?

IIRC, you need to set each item in a cell to be owned by a NPC by selecting the item then look for the Assignable Data at the bottom and change ownership to a NPC.
