Is it possible to add hidden fields at the end of card forms?

Hi,

I was hoping that we can add hidden fields to carry over data from our unique tracking links. 

How would we do that without disrupting the funnel of the form. If we add them at the end of the form it seems to carry the submit button down to the hidden field. 

Thanks, 

George 

You can add hidden fields at the end of your form. The submit button will be shown on the last active form on your card forms.

You can clone the form if you want to try it first: How-to-Clone-an-Existing-Form-from-a-URL
