Looking for a particular mod Thread

Hello,

So on a whim I downloaded and started playing DOW soulstorm and immediately downloaded the UA mod. It is absolutely amazing and has just about everything a person could want, however it does not have the ability for a player to use a different races units during skirmish. For example if you wanted to use IG artillery while using the tau. You can accomplish something similar with the sandbox function but it is not quite what im looking for. I was wondering if anyone knows of a mod that could accommodate this. I appreciate the help
