Didn't see the option either, but i also don't have an auto-sparge
If you follow the instructions on the electronic brewery website, they have some pretty good instructions on howto go about making your own holes, using the correct way.
But i also guess you could ask for the extra hole in the "Special Instructions" field during checkout. Most of the time i think retailers ignore this field when they package their stuff up. Just as a joke i always write in to draw a unicorn on the box. nobody has yet to date done that. Except for farm house brewing supply. where they wrote on the box "Sorry I can't draw". We got great amusement out of that..
