Primary Cargo and Cargohold Volume Bonus

[NonSequitor]

How about this idea?

Give each trader one or two primary commodities.

A primary commodity would occupy less space than a non-primary commodity.

Example: Synth Foods trader hauls synth paste. His vessel has a default cargo space volume of 3000. Synth paste is marked as a primary cargo, so the trader can pack 5000 - 6000 units of it on his vessel. If he decides to haul, say, mining equipment, on the next leg of his route, he'll only be able to haul 3000 units.

If this is too difficult and labor-intensive to implement, would it be a reasonable idea to increase cargo volumes on all freighters and transports? A 30% to 50% increase of cargohold volume would be gnarly indeed. Increased trading profits without goofing around with commodity prices. Fun for traders and cargo pirates alike.
