Zendesk Comments from Wall Posts

When a ticket is created inside Zendesk from a comment posted on a wall post. If a user comments on another user's comments, the comments are presented inside the Zendesk ticket altogether. The agents cannot respond to each of the comments. The agent can only respond to the main comment.

It would be helpful if Zendesk could look at improving this functionality to enable agents to reply to all comments, including the sub-comments.
