Aligning Faces in UV

Hello everybody, I’m not experienced in 3d so here is my question - I’m hoping someone could shed some light on my problem. Here’s the image:


And here’s the question:
This is what I get after unwrapping. Is there a way to align all those faces together in one simple step? When I press “W” and use align it works on vertices - is there something like that for faces? Thanks in advance!

Cheers!
