Big silent shout out to the spacefairers in the void.

Brief question: is there any way to retrospectively add customships to save game?

I built some custom ships that I saved as just templates without techs, left my game and lost the designs and now I'm trying to get them back.

I can get a hold of the ship templates when I start a new game, is there any way I can rejig the xml and/ or shipcfg files so that the templates appear in the save game which I designed them in (hopefully just the xml files but having fiddled around this looks less likely)?

Spent hours when I should have been doing something more productive building my empire and would hate to have to start a new game from scratch to get a hold of the ship designs I also spent hours on...

Cheers for any help...
