Labels over Post Brid Thumbnails

Hi there,

I was wondering if I could add personilized labels to the POst Grid thumbnails. Here is an example of what I want to achieve: REVIEWED books have a lable over them: https://www.gatesnotes.com/Books

In my case (see link in private) I want to add the Newspaper Logos as a label (Section: “The World Future Council in the International Media”), they would be different newspapers so I would need different lables.

Is that possible?

Thanks!
