Create a role just to moderate chat & Q&A

It woud be great to have the ability to invite people to become moderators of just the chat and Q&A function. The current method is to create a new speaker and then add them as a modertpr to a talk and then ensure they have speaker emails activated etc but there should be a feature to assign someone as a “Chat and Q&A Moderator” who has the abiliuty to allow questions to be seen and delete chat and questions.
