A question about terraforming pluses

[Blackavar]

I know that there's an option that you can place in the faction
file, "TERRAFORM, 0", that I've seen explained as halving
the raise/lower terrain cost. Is there a way to give a faction an
all around terraforming bonus? Say, like 50 or 75% time?

Never tried it. Might as well try some numbers in that ability and see what you get.
