[Hustle Pro] how to remove default form fields from hustle pro pop up

Greetings,

I have created a pop up using the hustle pro plug in. I would like to know if it is possible to disable the default form fields for a given pop up. The reason for this is that I have a pop up I have created in infusionsoft, and would like to use the HTML for the infusionsoft pop up to replace the default design provided by the hustle pro plugin. Is this possible to do?

Thank you for your help. I truly appreciate it.

Best, Nicholas
