Adding a property that selects based on the position of an item in the inventory would allow operating on a predefined set of items (for example only the worn armor or items in the hotbar).

A special value "selected" should exist that only matches the currently activated slot of the hotbar.

Technical note: Additional context needs to be provided to selectors, since the position of the item stack is not part of the ItemStack object itself.
