Changing values after game start

[PlanetNapalm]

I recently started a game with the Dark Nova mod. My race is Temporal. I just discovered that I don't seem to be able to upgrade my shipyard III to Temporal Shipyard I. I seem to remember reading that in order to do this I need to change the roman numeral for T.S. I,II,III to IV, V, VI.

Is is possible to make this change without restarting the game?

Thanks!
