More than 160/240 men per unit?

Is it possible to increase the unit scale above the "huge" setting of 160 men per "standard" unit? Ive tried changing the value UNIT_SIZE:XXX in preferences.txt. It seems to work, in the custom battle screen, but in the battle itself there are only 160 men per unit.

Is that a hardcoded limit, or is there some way go above it(and yes i know its going to be tough for my poor CPU :)?

I apologize if this has already been covered, but i was unable to find information about it.

Unfortunately, it seems to be a hardcoded limit indeed. Hopefully it will be lifted in the expansion. (It may have already been lifted in the patch, but I doubt it.)
