Customized banners

In my current town I operate quite a big army (about 300 soldiers) And it’s quite difficult to manage all my troops.
First of all limited variants of banners do not allow me to differentiate troops by their belongings and purpose. I want to use colors for grouping armies into main corps, flanks, reserves.
Also I was thinking about using banner’s background to separate armies by their unit type - for example - cross for heavy infantry, diagonal split for cavalry, vertical split - for archers and so on.

So what I want to see - ability to select separatly background and primary and secondary colors. Even this combination gives a huge variety of banners and will allow to solve different purposes.

Another thing - we can see in the bottom of the screen banners with icon of unit types within a group. But we have same icon for any type of infantry - light, heavy or pikemen, and same icon for lancers and horsemen. May be you can somehow differentiate that as well?
