Truck-Conveyor interface

A small building where trucks can unload directly onto belts or into pipes or where pipes or belts can load trucks. In a spaghetti base it's good to have an input material receiving point easily accessible, same as an equally accessible product collection point.
This allows players to build increadibly compact spaghetti factories where even some inaccessible buildings in the middle can receive fresh inputs from trucks.

You have already storages doing that. Maybe there could exists more compact tall storages, but the think is that pipes/belts are more effective to move resources than vehicles (except for trains at longer distances).
