Make "ford" terrain in world map reduce party speed like "forest" does?

[Gallus Domesticus]

Is it possible to adjust the effects of the ford(river crossing) terrains on the speed of parties?
I haven't found anything dealing with terrain in the module system. Is there any way to do this at all?

I believe that speed penalties on the world map are hardcoded.

Horrible kluge: make the terrain forest, and then cover it with a "ford" map icon?

Sigh.. I think I'll just put a few trees on both sides of the crossing then..
