iOS App - Marking Inbox Notifications as Unread

When a notification comes in on the Wrike App, once it is open it would be very helpful to be able to mark the notification as "unread". 

On the desktop version of Wrike there is a circle icon next to the notification that allows the notification to go back to "unread". Since sometimes the notification is opened by accident, or not yet ready to be dealt with, and having the notification marked as "unread" is another prompt to address it.
