Formations and more models

[chadics]

I was wanting to add formations and more models to the units as I usually do in civ4
but I found that many units share the same formation
My question is: Is it possible to add different formations for the units that share formation in a simple way?

this is what has me confused
all these units share the same ''default'' formation
