Independently move color readout markers across multiple images

I am trying to match the exposure of multiple similar images. I remembered the color readout markers in C1 and thought it would be convenient to set markers on my subjects forehead and shirt on all of my selected images. Currently C1 automatically sets those markers on the same X and Y coordinates on all the images which is probably good in many cases but since my subject moved a little bit on each image the markers might then be on a different part of the face or shirt and if I move a marker on one image it is moved on all the other images as well. I tried holding crtl, cmd, option and shift while moving the marker but it did not make a difference.
