Is it possible to sell things in a similar manner? I've tried holding down Ctrl, Shift etc during sale, but it won't sell the whole stack.
If not, they need to add it in, because I have to sell in a hurry, lest a Deep Space Encounter decides that I've sat still too long!
Sell to a vendor and not the replicator, you'll be asked how many of the stack you want to sell. If time really of the essesnce, any stacks you're selling to the replicator will end up being so worthless you're better off just discarding the whole thing with "Discard Stack".
