Hi Lauren,
The new options: -max_areas, -max_search_radius and the environment variable AFNI_WHEREAMI_NO_WARN should do what you want and more. See details in (upcoming) whereami -help.
You will have to wait until new binaries are posted. Watch for an announcement regarding the Anatomy Toolbox data late tomorrow. You will need to update AFNI binaries and download the latest Anatomy Toolbox datasets.
cheers,
