Request for a change in Newtown shops

As there is a cooldown time for shop signs now, buying items in quantities in larger quantities have become more time taking. A simple solution to this can be adding some signs selling same item in larger quantities like 16 or 32 depending on the item. This would be particularly good for the ore shop in newtown as stuff like iron, redstone or lapis are rarely bought in small quantities. I request for addition of signs selling larger quantities in the newtown shops. Thank you.
