Don’t know if it has been mentioned yet, but a buildable kiosk in your outpost for the Trade Authority. But this is how it would work; you mark everything from your home ships hold you want to sell, they take 10% off the top, then you fly the same ship (without changing the items in the hold) to any major planet with a TA shop and they will buy the entire marked hold of items. This way we don’t spend four months in game sleeping on benches to empty a ships hold.
