Adjustment layers when using split screen and individual views

[n0n0]

How can I apply an adjustment layer to each person's individuals tracks (V1 and V2), without having to manually duplicate/apply the same adjustment layers to the same tracks being used (nested) in the split screen track (V3)?

I am switching between 1 and 2 screen view using a split screen template with the nested tracks.

What is on the AL.

Cannot you apply to the clips directly? Or as Source clip effect?

I have not yet used a source clip effect, so I will look into how to do that.  Below is additional information about my question.

The AL includes color and light adjustments. But each track is being used twice, once in the nested track, and again in the main sequence (on either V1 or V2), so if I apply the adjustment layer to only one, it won't apply to the other (same clip) when I am switching back and forth between split screen and single view.

V3 is the split screen view with the two nested clips, and V1 and V2 are for those same clips (single view) so I can switch between split and single view as I edit. 

I want to make different adjustments to the two clips I am using, otherwise I would just apply one adjustment layer over it all.

Is it the same adjustment layer? If you put one above the nested clip in your picture, it will effect all '3' clips. If the AL is different for the two tracks, then perhaps apply to the Source Clip(s) as Ann noted would be the way to go.
