Can anyone explain please how the "load/unload fuel to set level" works for Fuel Harvesters that have mined Sorium and then wish to unload part of the resultant fuel at a colony. There is the unload 90% order which works fine but what if I only want to unload ( or alternatively load ) say 60% of the fuel tank capacity? I can see no mechanism in any screen for stipulating a percentage other than 90%.

Edit : Ok I found the box at the bottom of the screens and after trial and error I was able to order the FH to unload part of its cargo.
