Hello @MattB378 ,
At this time, there isn't really a way to edit the unsubscribe form. Since there's a lot of legal and Compliance-related elements tied up in the unsubscription process, we've tried to ensure it be as straightforward as possible for contacts.
With that said, our engineers are exploring way we can give a bit more freedom with the unsub form's customization / wording, while still honoring those legal and Compliance expectations. I've submitted your case to our engineers, so that if and when they have an update they'll make sure to notify you.
