SSE Have item in favorites but not in inventory?

[TheDoodlerDude]

Does anyone know a way to make an item appear in the favorites list but not show up in the inventory? I'm trying to create an OP necklace for my SSE save that doesn't show in inventory.

An item can be favorited and not in the player's inventory but it will not appear in the favorites list. In order for a favorited item to appear in the favorites list it must be within the player's inventory.
