"For each level of Tradesman the player has, they will receive either 3 silver worth of product or 5 units of Raw Material at Logistics. The 3 silver worth of product will be a mundane item related to the Tradesman type. Items are considered to be ‘mundane’ if they are not specifically used for or created by any other skill (eg: Mithril or a shield for blacksmithing) and cannot be used for any in-game mechanical effect (eg: alcohol). The RM will be mundane except for its use as RM. This can be divided up into multiple item tags with low value, or combined into a large single tag with a higher value. A jeweler could receive a necklace worth 3 silver, or 5 units of RM of chain usable by Trappers. An herbalist might produce 5 units of RM usable by Alchemists or 3 silver worth of mint. Players must choose which type of Raw Material (maximum of one) the skill can produce when it is purchased and have this approved by a Logistics Marshal. You may also combine different Production skills to create a single item, such as a dagger (made by blacksmithing) with a gem in the pommel (made using Tradesman: Jeweler)."

Question

The above quote isn't super helpful, but it's the closest thing I could find. Can you make a physical mark on a tag which is then a mark on the IG item? For example, could I draw a star on the back of my Goodberry scroll, and then if somebody steals it from me, I can say "this is mine, it has the star on the back"? Or do the same for an item tag like a toy - the toy now has a star on it.
