Since the game allows for advanced piers to be made exclusive to specific commodities, it would be logical to also allow these structures to be made exclusive to (any number of) specific ships, or a specific trade route. This can help to optimise the incoming ship traffic for specific bulk quantity imports such as coffee, and prevent more than one ship trying to simultaneously offload the same good. The pier can be customised by having a drop down menu, and being able to tick the names of the ships allowed on that port. Alternatively, each port can have a unique numerical identity, which can then be assigned to a specific trade route in the trade route menu.
