Is it possible to groups fields into one rule

Is it possible to groups fields into one rule

Hey,

I'm using the validation plugin from http://jqueryvalidation.org/ and i have a small problem.

I'm trying to make a validation rule that validates whether one of N checkboxes are checked.
My checkboxes do not share the same name, so i'm out of ideas.

I've made a small sample to demonstrate my issue:

Hoping that someone can help me out :)
