QuestionPro - Research Access Forums

Hello, I was wondering how to add a comment box to each question without making an entirely new question just for comments.

For example, I'd like to a question like this:
~~~
Rate your satisfaction with this vendor:
1) Satisfied
2) Neutral
3) Dissatisfied

Additional Comments:

~~~
Is there anyway to combine the comment box with the rating system in one question? Thanks for your help!
