Best way to export wordpress comments from Coursepress Pro Discussion

Hi Gurus,

I'm wondering what the standard practice is for exporting wordpress comments from coursepress pro discussions? The discussion topics themselves, for the most part, will stay for each new round of students in a course. But I want to be able to export and remove comments after each class.

Presumably, I'd like to be able to parse the comments for future topics and answers.

Is there an easy way to do this?

Is there any connectivity between CoursePress Pro and the Support System or Q&A plugins?
Could these be used instead of the basic wordpress comments used in coursepress pro discussions?

Thanks kindly,
