help with adding missile turrets... any ideas?

Assuming you have more missiles in cargo, wouldn't restocking the launcher simply be a matter of pressing 'B' and then dragging more missiles back to the slot? I mean, this is how you "refill" fighters right? They dock with the mothership and then you can swap out missiles (or any other module for that matter). The only problem with the mothership is having to allow it to drag missiles into the slot while flying. Otherwise, as Goblin Wizard says, you'll have to dock to reload.

I agree that not being able to toggle them off is a serious nuisance, but you could fly around with the slot empty so you won't waste missiles on common riffraff, and then drag some missiles to fill it in when you see a suitable target. Of course, assuming that we solve the problem of being able to drag the missiles to the appropriate slot on the mothership while in flying.

Er, can someone with ship modding experience test this?
