This relates to the dual use of "class name" with "filename"
On the build popup their is the "Suggest" button.
When you hit it the first name it will use is the name the ship design was saved under as it assumes that to be the class name.
To manage the many designs I used a save name that is a code like "BB v006 16in" thus I keep getting that as the suggest if building only one.
Likewise my DDs with their many designs as tech changes will be like "DD v009 t1100". So when I order 8 of them one of them will get the filename for its ship name.
After many play throughs of the game cool ship names would be used in different games for very different designs. So the Emdem of this game isn't the same as before. The Yamato of this game might be different as well.
The request then is to add a tick box on the build screen to exclude the filename aka "class name" when using the Suggest feature or the auto-naming.
