[NTG-context] Adding supplemental information to entry in list of figures

Hi all, \nolist{}, I understand, is used in headings and presumably in captions as well to exclude parts of the heading / caption from the automatically generated list of contents or floats. Now, my question is what the canonical way would be to add information to an entry in a list of figures that doesn't appear in the caption to that figure; indeed, it might be desirable sometimes to specify the entry in the list of figures independently of the caption, very much like the LaTeX command \caption[entry text]{caption text} does. Thanks for your help, Elias
