How can I scale faces without moving them? I'd like to scale all outer faces of an object without making it smaller.

So in this case I want to make the selected faces thinner(scale them on the x and y axis), but WITHOUT being moved to their origin.
Or in other words: want them to scale to their own origin instead of being scaled to the objects origin.

Of course I could scale each of them individually, but that's a real grind and I wonder, if said thing is possible.
Use "individual origins" pivot option:
