Spreading out with 5 characters

Is it possible to spread out with five characters like so using a keypress?

---X
X X X X

Formerly I've used four characters and it was rather easy to just bind the strafe to two while one remained inactive, so I would press a key and go from this;

X
X

To this

--X
X X X

I'm sure there's something you could do it you bound the keys of move up, move down, turn left, turn right, but I prefer to keep those bound to the arrow keys (up, down, left, right) because when you're multiboxing hunters you need those keys to move back when melee characters close in on you.

i do this with 2 keypresses, playing 5 shamans

1 in the lead (always a step in front of the alts) who does not react to either key

, key makes 2 chars strafe left, and 2 chars strafe right
. key makes 1 char who just strafed left, strafe right, and vice versa for one char who strafed right to strafe left

press , for 2 seconds followed by . for 1 second
