Building for loading / unloading

A small building with a "booth" or platform for a truck on one side and a universal entrance / exit for pipes, conveyors and other things - on the other. The main feature - you can tie a truck and assign the type of cargo. Another (possible) one is loading the resource from the truck directly to the conveyor.
In order not to break the balance - can add a worker or limit the types of resources.
The main idea is to have a separate truck deliver resources to or from a separate point - regardless of the assigned priorities.
Not the main one - I don't really like the current option when resources get into buildings from trucks using "magic". and trucks poking into the building from all sides is somehow strange.
