Hello, would it be possible to implement a system where, like the ingots on the ships, we could apply something, be it ingots or gems or something else, to the trains to increase the likelyhood of getting a certain supply, like hammers or saws? It wouldn't have to be a guarantee thing like how the platinum ingot only half certifies getting a treasure chest, but increase the chances for someone who has too many paint cans and would rather increase their chance of getting nails back next. Thank you.
