[Hustle Pro] Prevent popup open after form submit

We are using the Hustle Pro plugin, and we’ve currently got a pop-up with an embedded gravity form. It works great, but we realized that people who are filling out the gravity form are being prompted again when they go to a new page or open another session. Is there any supported way to work around this or would it require a more custom approach? Basically, we want the popup to NOT OPEN for users who have already submitted the form. Please advise.
