Yes it can. open all photos in camera raw, adjust white balance, then with all photos selected and corrected image displayed , choose white balance select tool and slect the an appropriate point in the image. All images are corrected. It even corrects the images in the background while you go back into photoshop to work on other images.
sorry, forgot to specify i was taslking about jpgs or tif's not RAW.
Of course all thew RAW convertors can do it but only with RAW files. in my earlier post i had said that the main reason i use RAW was because of the quickness of editing multiple images but have since found i can do it with jpgs in Picasa2.
