In the endgame I have 400K units on my cargo dock. This makes it very hard to adjust ore ratios and thus very hard to solve some balancing issues I am having with having too much Iron (20x 400% smelters!) and not enough Titanium ores.
I would like an ore sorter that splits my main pile into different outputs so I can construct bulk storage for each ore type and than either remix to my liking or revert back to single type refineries OR add multiple inputs to the multi rigo.
