Mark as Read Button in Pop-Up Notification

I like to keep informed of what's going on in my teams, so it's useful to have the pop-up notifications, but it would help a lot if there was a 'Mark as Read' or similar button that could be clicked on in the pop-up itself (a feature some email reader apps/browser add-ons have) so I can quickly set aside things that I know don't need my attention without having to navigate to Ryver.
