Full stack of items into a currency exchange?

Is there any way to put a whole stack of items into a currency exchange with one click, without having to enter the number of items I want to sell each time?

not on initial entry, no. If you are doing multiple stacks, it will remember last set.

Example: You want to sell 300k juice in 50k stacks. You can set the price for the 50k stack, then click place order 6 times.

Or, you can go in reverse, and just set the amount of chaos you want and clear the juice amount and it will auto fill in the required amount of the chaos (tho you are subject to current market buy price instead of sell price this way)
