Good point. Separate piece would be better. This also gets us to cargo handling robots, though most free traders would need anything that expensive. Starports and warehouses would of course.
Also to Derek's point, a case could be made for there being a Cargo Handling skill (and if memory serves, there isn't one), since while grav modules might nullify weight, they do not nullify mass. There is more to managing a warehouse and loading a ship than just stacking oversized Lego blocks, even if cargo containers are standardized. Not exactly the "sexist" skill on the chart though PCs who don't know what they are doing could create serious havoc without it.
