How to unwrap identical faces on top of each other?

I have a model in which I have multiple identical faces. Instead of giving each face their own coordinates in the UV map, I would like to lay them on top of each other. Only there are a few dozen of identical faces in my model and it would take forever to lay them on top of each other manually. Is there any lazy way out?

Here’s a screenshot of my situation.


You can unwrap a face and copy that face UVs to other selected faced with the Copy AttributesAddon that comes with blender


It’s working great, thanks!
