Changing color of multiple hue bulbs at once

Probably not the best place to put this question and I wasnt able to find an answer with google. Is there a way to quickly easily change the color of a multple phillips hue bulbs at once? I already have them grouped by I have to change each one at a time. Also can I dim both at the same time?

There are custom apps in ST community floating around.

If you want to go non-smart way… I love and use OnSwitch and QuickHue iOS apps a lot…
