Separating Multi-Mapped Fields

Hey there,

I’m trying to submit a multi-mapped field from Contact Form 7 to Pardot. The form is located here: https://www.pyapc.com (Form at the bottom of the page). The fields in question are the checkboxes. The Pardot field to which this form’s checkbox is mapped must take each value in its own parameter. For example, here’s what is submitted with the multi-mapped option:

https://link.pyapc.com/l/805013/2019-12-01/6hql?email=test%40test.com&;firstName=Test&lastName=Test&newsletter-select=Healthcare+eNewsletter%3B+Tax+%26+Assurance+eNewsletter%3B+Webinars

I’m wondering how to make it submit as follows:

https://link.pyapc.com/l/805013/2019-12-01/6hql?email=test%40test.com&;firstName=Test&lastName=Test&newsletter-select=Healthcare+eNewsletter&newsletter-select=Tax+%26+Assurance+eNewsletter&newsletter-select=Webinars

Thanks for your help in advance!
