So you can hide items on locations and hide yourself with your items in you, but you can't hide items withing yourself or your inventory.
The idea is basically you can hide relatively small items in your person and when searched by other or pass through ambient security still have them in your person if not found.
I wonder if there is a coded reason why something like this would be difficult to implement or if you could just use the same mechanic for hiding objects in places but within your inventory, maybe using a different wording for it.
Anyway, that's my idea. Yay.
