The Situation
Currently when trading with other players using contracts, whether buy, sell, or shipping contracts, one can only select one item/one resource per contract.
(Eg. One contract buying DW, one contract buying RAT, etc.)
The Problem
Having only one item per contract gets quite tedious when trading often with players directly when multiple items/resources are at play.
(Eg. Having to restock DW, RAT, OVE, COF, PWO at the same time and having to make a separate contract for each)
The Solution
The direct solution would be to allow multiple items/resources per contract. (Eg. by bundling them)
