cell Comment allow @username to share content or assign task to a user
Please allow use of @username in comments in online Excel, such that someone can be directed to a given cell in case they need to be made aware of some information or a task can be assigned to that user. E.g. if someone needs to add some content, or confirm content, they would get an email to look in a particular cell or row to edit or confirm.
