How can I place question as a host to Q&A

I would like to ask you why as a host I can not write question into Q&A? For example: we have webinar and the Guest answers only the questions in Q&A, but some attendes join webinar thrue the browser and they can not write answer into Q&A. As a host I would like to help them and copy the question to Q&A but I can not. I hope you solve this problem, you are perfect team:-)
