Would it be possible to have the distribution end on the release of the CTRL button, instead of relying on the delay? When I'm distributing over many machines, sometimes I get caught on one of the machines and can't reach the rest of the machines before the delay ends. But if I set the delay to longer, I now have to wait for the distribution to take place before I can chose another item to distribute. If I chose another item before the distribution takes over, every item previously distributed, like copper plates, gets overwritten with the new choice, like iron plates.
