My suggestion is simple to buy bulk in the store only you click on the consumable you want and then there is a type/up-down count system to allow you to buy in bulk. Similar to selling multiple items in the inventory system.
Let me know why you think, and it should be easy and simple improvement to the UI for users to use and to come.
I truly do hope PGI take notice to something so small but is also a positive suggestion.
