Modding multiple shipyards per planet?

So, what you do is:
a) Add a new facility, with the same family number as your spaceyards.
b) Give it a roman numeral of zero (less than any true space yard)
c) Remove the space yard construction abilities.
d) Name the new facility something like "Spaceyard Expansion Project", and have it cost 50,000 organics or similar.

I don't understand that...why the way to mod this is not :
a)Add a new facility, with AN OTHER family number than your spaceyards.
b) Give it a roman numeral of the number you want due to your level number(differents levels of expansions)
c) KEEP the space yard construction abilities or one of them if you want to make specialized expansion and if you want add some to put a maintenance cost to these very usefull facilities....
d) Name the new facility something like "Spaceyard Expansion Project", and have it cost 50,000 organics or similar.

Maybe i haven't understood nothing to modding...it might be that.
thanks for youre answer !
