I'm thinking, add button on city for use stock can ease the use of stockpiles, because actualy we need to click on one and select yes again and again to use much stockpile, at the end, using stockpiles it's boring , What do you thinks about this?



P.S. sorry for my bad english.

It's not a balance suggestions. Yes we need a faster way to use all stockpiles at the same moment on one city.
