How to turn on the battle banners?

[Ognjen Todorović]

Battles are epic, but keeping track of what unit belongs to me and what belongs to the opposition (especially in Roma vs Roma) is really hard and gives me a headache because of my confused staring at the screen. What I want to know is how to turn them on?

Edit:
Figured out the way to do it, all you have to do is change SHOW_BANNERS:FALSE to SHOW_BANNERS:TRUE in preferences.txt (Located in preferences folder inside your RTW folder).
