Location of Faction Symbols?

[ffhc2001]

First of all, i'd just like to say I LOVE this mod.

I was wondering however, where I could find the campaign map faction symbols. I want to change the Roman faction symbol back to the standard Julii symbols. If someone could tell me where the faction symbol, the campaign map banner symbol as well as the commander button in the batle map along with the battle map banners are located in the data folder? Thanks for your time.

This is more of a modding question, so moved to the Workshop.
