Soup/Potion Pail

Soups and potions are not used to there full. I feel that this is because how much inventory space they take up, but what if the was a soup or potion Pail in Minecraft? The pail would overate like a small storage system that you can buy in your inventory. Kinda like a backpack put you can only put soups and potions. It would have only 6 storage spots so that it is not totally game changing, or could even have more expensive versions that It could have more slots. Thanks for reading.
