Would it be possible to have more than one person in the chariots included in this mod, or is there a technical limitation that locks it to one?

The Hitties, for instance, would have had three men on a chariot: a driver, a fighter, and a shield bearer. The Egyptians, I believe, would have had two.

Additionally, is it possible to allow for dismounting from chariots? Perhaps its anachronistic to this era, but didn't the ancient Greeks primarily use the chariot as a means to transport their warriors to and from the front lines, negating the need for men in full panoply to march long distances?
