Is there a battlefield map mod for Dom III?

[Epaminondas]

Back in the olden days when I used to play Dom II, a helpful soul made a battlefield map mod of sorts where I could easily pit any types of units against each other to test how effective certain units or unit combinations were against each other. Is there a similar mod for Dom III?

Thanks in advance.

P.S. Basically, I want to test various units against each other to test their combat effectiveness. If this can be easily modded myself, please let me know too.
