Elaborating a bit on what cfg said:
- nest every camera angle you want to colour correct with an adjustment layer;
- apply colour correction onto adjustment layer, cutting it into several pieces if the camera angle consists of several groups of clips, which require slightly different grading;
- build your multi-camera source sequence out of those nested sequences.
Even though you missed nesting with an adjustment layer step while building your multi-cam sequence, you can do it at any time you want. Even after you've done with cutting your target multi-camera sequence.
