Why can't trading Jade for staircases have the "amount bar" you want to buy(like when you buying seeds)

On PC, holding down SHIFT button and clicking, buys multiples. Still not much, but at least it isn't 1 + 1 + 1

This! I wish the dev would make this a thing. This is why I've been holding off trading my Jades 🥲
