I think if you look on starfleetcommand3.net under resources you'll find a program called core edit. I know it fools with the hardpoints of a ship, but not sure if it does what you're talking about. To edit the hardpoints direct look in your defaultcore (opened preferably with excel because it's tab delmited) and you should see stings of numbers that look somewhat like this - 1:370_30
Those are the harpoints and what direction they face. Each string is made up like so, Hardpoint:Arc.
