On Facebook, can you change a notification from "Read" to "Unread"?

[Squirrel]

There is now a little circle next to each notification and if you position the cursor, it will say "read" or "unread". Is there a way to mark something you have read to unread?

You can do that for Messages, but I don't think you can for notifications. If you click the circle next to the notification, it doesn't do anything.

Yes you Can Go To your Inbox Under Each Message you Will See a Circle That Says Mark as Unread Click on that And it Should Change it From Read to Unread
