Shopp Plugin Product Page Template "Ask Seller" Button

I love the functionality I have seen so far on Shopp Plugin, but there is something missing on a product page that I saw, I want my customers to be able to click on a “Ask Seller” button to allow them ask question about the product they wish to buy. On clicking this button, there should be like a contact form pop up display. Or if they can just have a small contact form on the product page altogether.
Does anyone have an idea on how this could work, or if Shopp does it out of the box?
