Is it possible for you guys to modify the available formations?

I'm not a big history buff, but I feel a little guilty every time I set up my units in the battle map in an ahistorical manner out of laziness. I typically set up my lines like this:

Hastati - - Princepes - - Hastati
------------Triarii--------------

Do you think its feasible to make a formation option for the standard roman battle line? I would without question use it to get the real feel of ancient Roman warfare, but I don't want to move every single unit in place because it is sloppy and often formations reset without me giving the command.

I'm sorry if there is a thread on this and I should have searched first, but im stubborn and lazy.

brother i have a solution and you will be quite pleaased; use alt click and your formation will retain its shape

Wow that is all it took, thanks a tonne. Those pesky formations gave me so much trouble.
