[Plugin: Subscribe2] Making category choices available on page with subscribe form

I like the simple form, but I wanted to be a bit more detailed. Is there any way to post a snippet into the plug-in to allow me to have the categories with a checkmark that the users wants to subscribe to on the page I put the token on?

They would checkmark the categories they want on the page and fill out the email spot before clicking, instead of just subscribing. They could see before hand. I wanted to do this on a fiction site and the categories and subscribing I thought would be an awesome idea.
