I’m in the same boat as you buddy, and i believe we may have shot ourselves in the foot. One of the things I did try though was to color correct one of the angles, copy it in the timeline, then select the same angle where ever it appeared throughout the sequence and paste attributes (a window will pop-up, check the “filters” box) onto all the selected clips in one shot. Whatever color correcting changes were made on the first clip will paste onto all the clips that were selected. I tried correcting the source clip and didn’t see the changes in the sequence, so i think this might be the best way.
