ENH: Automatic recording of erroneous locations/ROIs

[raamana]

It would be very useful to automatic record location (image coordinates) or ROI name (parcel annotation perhaps?) of erroneous areas as users identify them. They can note it in Notes field right now with hemi:roi_code; etc but it is additional work (even if simple/quick) and sometimes users may not know the name or hemispheres.

these location codes can be very useful e.g. as inclusion or exclusion criteria for certain studies and goals
