Can we pick the size of the box that the cargo hauling mission will spawn?

No. Not currently. It's something that we'd like to get to on the design side, on the mission design side, because it gives more ability for the player to pick and know how they fit. Say you're doing some emergent economy trading with your commodities, right? And you've got space for a little bit of extra cargo and you're going to the same place. You've spotted a mission that goes to that place where you're going to sell your goods emergently. You might be like, right, well, if they were all in two SCU boxes, I could fit more in. So we want to get to that direction.
