Multiple buy option in shops

Can we please have option to buy multiple items at once when applicable (ie for keys, chests, orbs, blue essence, etc.)? For example you can buy 10 Blue essence for 1 world coin to burn off random leftovers, but it's all the way down at the bottom. You have to scroll down, spend 1, then scroll down again and again. Just let use spend however much we want in one go.
