For me there is some merit in this Idea. I like many others, don't build armies from scratch, instead I create a random army and spend time "Tweaking" each Corp, I rarely find the initial army created balanced to my liking.
If I could create randomCorps, defined by CEH and type (Infantry, Artillery, Cavalry, Mixed), I could build my army from the bottom up rather from the top down, without having to spend the time building it from scratch.
