Annoying feature about the speed values in AI_Design_Creation.txr

[Nitram Draw]

Trachmyr,
Could you get the effect you want by adding an extra standard move and extra combat move ability to each base hull type? It won't solve the space problem but it may be easier to accomplish, the AI would automatically get the ability.
I don't know if this ability will work on hulls but I have added extra supply to a scout hull type and it seems to work.
