make comments on product page separate from reviews

Hi there,
I want to use the plugin for products. Is it possible to show the comment tab as a separate tab from the review tab. So I would like to have the review tab and an extra comment tab (named questions) using wpdiscuz. How can I achieve this? (I know that Woodiscuz does this however I want to achieve it with wpdiscuz). Is there a function I can use?
