Food store to receive more than one product.

Many times found my pips die of starvation, yet due one time to not knowing that I could only select one food item at the store and that despite vegetables being both stored and connected via belt, were simply ignored. I had to have another store for the veg and wondered why, when each store lists the products so clearly.
Please, make the one store function like a store for all products and allow the lorries to then load to the storage if connected and not the store if not connected.
