Explain your idea

Refinery lacks input slot on multiblock to automatically pipe in items to catalyst slot. This is relevant when, for example, creating Acetaldehyde and silver plate is needed in catalyst slot, but cannot be automated as there is no slot to pipe in items.

Similar to the Fermenter, the Refinery should have a slot in the front or back that accepts item input for the catalyst slot via item pipes or conveyor belts.

Catalysts are not consumed. They do not need to be automated.
