Sure, you could just go into your keybindings and set each one to a different key, though you might be better off setting them all to a set of movement keys like the arrows on the keypad or something like that. This way, if you had an AoE effect like the ones Nazan uses at the end of Ramparts, you can just tap the left key and move them all left each time to the wall, then tap forward to move 'em all up a bit, then go back to the right. That'd give you the most movement potential without having to worry about one of them tripping on an already dropped AoE spot. For precision movements for each one, you'll either have to bind a lot of keys or switch windows to the one you want moved.
