I don't use any of the default formations, because they're no good for the Roman quincunx. It does get a little annoying having to carefully re-order my troops at the start of every single battle, but what's worse is when I sometimes try to move them all, and it tries to re-order them into a single line. Thus I then have to move each and every single unit individually, to preserve my formation.

Is it even remotely possible to delete or otherwise negate the formations that are there for the player?
