I have asked before but it came to nothing.
I think all shipyards that well a certain size of ship should have corresponding outfitters that sell all the mods for it at least up to grade C. I bought a T7 but couldn't buy a better FSD for it at all and the stock one wouldn't even jump out of the system to the next nearest system. I had to strip it down almost to bare bones to get it out of the system to a station that had the FSD upgrades for it. Seriously, the stock jump ranges are crap on almost ANY ship.
Being able to use another ship to go get the FSD I needed would have allowed me to use my T6 to fetch it. Instead, I had to strip my brand new T7 down, run it without shields to get there and rebuild it again when I arrived.
