ACR Relative Adjustments

Hello everyone.

Is there any chance of seeing relative adjustments in ACR? There is a basic implementation of it in Lightroom CC, and would be a very welcome addition to ACR. Let me explain.

For example, I have two RAW images shot with Auto exposure. I adjusted the exposure of the images in ACR to match each other (say, +0.5 and +1), but now I'd like to make both images a bit brighter by the same amount (+0.2). The only way I can do this now is adjust each image separately to maintain their current previously adjusted exposure values. It would be great if I could select two images and add a relative +0.2 amount.

The same refers to most other adjustments.

Thanks for any reply in advance!
