Product subtitle?

Is there anyway that i can add a subtitle to my products? For instance, I am selling a single on my band’s website and it comes in the form of a digital download. I would like to display the name of the track as the product title and have “digital download” as the subtitle. Now I have got this working on single product pages using the Visual Subtitle plugin because it allows subtitles on posts. I am looking for a way to include the subtitle on the products page for each product. Can anybody help?

Thanks

Adam
