In Lightroom, if you select a bunch of photos and turn on auto synch any change you make in one photo will be applied to others. So you have one photo with a white balance card in it, and then a bunch of other photos taken under the same lighting but without the white balance card (unless you find white balance cards to be aesthetically pleasing, in which case you can keep it in all of the photos). Click on the white balance card with the white balance eyedropper and it will correct the white balance in all of the selected images. It does not matter if the individual images were shot with AWB or the same fixed white balance setting, they will all end up with the same white balance after you do this.
