UV's - Is there a way to orient all the UV's of a polysurface, at once, using Rhino commands?

UV’s - Is there a way to orient all the UV’s of a polysurface, at once, using Rhino commands?
Or using some automation of combined commands?
If possible send an example.
Thanks for your attention,

Hi Leandro - not for a polysurface, but if you explode and run Dir, (or ShowDir) then you can align per face on the entire selection. These should survive Join. What are you trying to accomplish? The visual feedback from a lot of surfaces at once can be a bit confusing.
