Is it possible to create new Attributes?

I was wondering if anyone knows how we can mod in new Attributes for Medieval 2? (command, authority etc..)

Is this even possible and what file governs that system?

Not to my knowledge, I think it is hardcoded.

I know that you can change attributes of units and make new units and give them the attributes you want from the available list of attributes .

This is an older title of the series, no assembly Kit for it, you need to unpack many files etc and lots of txt editing and workarounds. In some ways more fun to mod than newer titles though :)

In others, much more frustrating hahah!
