I was looking for the same thing. I wrote a simple one, no emailing the league or any bells or whistles. I'm not trying to sell something, just needed one for our live draft - drawing from a hat got tiresome.
I'll open it up to whomever needs it until someone decides to screw with me and abuse it.
put some instructions at the top, but I don't want to spend longer than the 20 minutes it took me to write. hope it helps:
