Honestly, I feel like the "proper" solution is smarter trade slave orders. Right now, you can really only have 1 slave handle 1 type of commodity because if you try to do two things, say bring nuke waste from station A to station B and bring rations from B to A, he's liable to get full of one commod and not be able to perform the other job which can then result in a dead base.

What we really need to do is extend the trade slave orders to something like "Buy rations at a price limit of X up to a quantity limit of Y". Then you can have your slave with 1000 free hull space buy rations from one base up to a limit of 500 and buy nukes at another up to a limit of 500 and not worry about getting full of one to prevent the other from working. This would let us make trade slaves that could do double, triple, or quadruple duty of what the trade slaves do now.

This wouldn't help with mining slaves, but I don't really want to make mining slaves more powerful anyway.

A simple "Toss Commod X" order would work great but what we really need is for the slave to recognize when it is out of a commod. As in, if I have a slave supplying rations to 8 bases what I do is tell it to go to supply, sell to 2 bases, go to supply, sell to next 2 bases and so on. This is incredibly wasteful in some cases or not enough in others. What would be great is to set a specific supply base and then when the slave runs out of the commods it is selling it will return to the supply base and continue where it left off.
