does anyone else think it would be a good idea, not to mention easier to be able to upgrade individual systems on a ship, rather than having to upgrade then entire ship, resulting in several ships bearing the same name, just with different "mark" notations?

for instance you could just select an option to upgrade engines, select the new item, and easy as that, your ships are now upgraded with the new propulsion, with the appropriate costs of course. or just telling the ship yard to upgrade the engines would automatically add the new engines to all ships being built from that point on

i dunno, just a thought
