How to upgrade ships
I'm fairly new to playing Gal Civ II. I've noticed when I upgrade my ship designs the only way I seem to be able to upgrade my old ships of the same type is by paying for it. Is there a way I can have my planets upgrade the ships manually (like they do when building new ships). So what I want to do is when I upgrade, lets say my Fighter from I to the new II level (with more advanced weapons/defenses) I want to be able to que my factories to do the upgrade instead of spending 300BC or so per ship to upgrade - is there a way to do this?
