Subject Communication Notification

When a new message is received from a data subject, the current notification is just to have that request highlighted in the queue for the person it was assigned to. It would be great to instead have a symbol like a filled in circle near the request to indicate there is a communication so that everyone that has access to the queue can see there is a new message instead of just the person it was assigned to. If you were to keep the highlighting that could work as well but then the suggestion would be to add an option to the request to mark the communication as read. Having the mark as read option would help users accessing the queue (not just the assignee) to be able to see that there is a message that needs to be read. Thank you!
