hidden field class identifier value

It would be beneficial if the field label were somehow included in the HTML of the form's hidden fields as a class or if you could add a CSS class parameter so one could use something like .class-number for a hidden field used on multiple forms without having to use the ID (#input_x_y) for each form's field. Or if you have multiple hidden fields on a form, .course-number and .alternate-course-number. This is useful for making jQuery selectors for populating the fields dynamically from modal window choices that can be reused across multiple forms. Relying on the #input_x_y becomes messy when exporting forms from one server and importing them into another as form IDs are not necessarily the same after the import.
