Setting cellStyle and titleStyle for the whole form

SmartClient Pro 9.0

Is there a way to set cellStyle and titleStyle for all elements of a DynamicForm at the time the form is defined? I see that I can set this on individual fields, but that is kind of a pain when I need to update all of them.

I'm currently thinking of getting into the form's initWidget and looping through the fields array, but I'm thinking there ought to be some property that can be set for the form.

Thanks,
