Changing Casse bodyguard

Hi guys - sorry if this has been discussed before, but how exactly would I change the composition of my Casse bodyguard?
I'd like to switch it so it can be Calawre and eventually Rycalawre (after reforms), I just can't get into the chariots at all :S

I'm playing on Alex.exe using Jirisys' MegaModPack 1.03 by the way.

Thanks!

Try the forum search function, this has been mentioned several time already.

Aaah, thank you. Should have remembered.

Problem is completely solved now.
