The same way Nappy did it in his day: Don't move individual units, move larger standerdized divisions around. In the early stages of manouvering around and picking positions this helps a ton... when armies clash it still gets chaotic and overwhelming but who cares if a unit misses their turn? Its already in place shooting in the general direction of your enemy.

(Picrel: 5 inf 1 guard is the perfect standard division and any anon that claims otherwise is lying on the internets)

Also the hotkeys help a lot.
