Reply all for comments and tasks/campaigns

As an Optimizely user, I would like to be able to quickly and easily tag everyone in a task or campaign in the comments or "reply all" to everyone in a comment without having to @mention each person so that I can be sure everyone gets the comment they should.

More details:

Would like the ability to reply-all to messages/comments without having to individually and manually tag everyone in the original message. This could also apply to a campaign or task where we need to share an update with everyone involved.

For example, have a "reply to sender" and "reply all" option that auto-tags the sender or those who were also included in the original message.

Having to manually tag each person in a comment isn't a good user experience and can cause errors and issues.
