Can you have two different buttons for your product and for the form submit on that same product?

On my site I have a product that is an annual membership. For the product itself, the buy now button says "Join Now". Before the payment screen, I have a form that they must fill out that was set up under the product. The button at the bottom of the form mirrors the product button, and so it also says "Join Now". I don't like having the "Join Now prompt twice. It seems like you're asking them twice if they want to join. Instead, I would like for the button at the bottom of the form to say "Continue to Payment". Any idea if this is possible with code? I'm guessing probably not, as this is part of the checkout process, and SquareSpace is overly strict about being able to edit anything in this part of the process. Any help is greatly appreciated. 

1. You can add the form to the product so that when they click Join Now, they get the form in a Lightbox:

2. You can add the questions to the checkout page depending if you have other memberships or products:

Thanks for your suggestions. Unfortunately they aren't workable solutions for what I'm trying to do.
