[NTG-context] Re-start figure numbers

Hello, I placed 150+ tiny images (distributed over several chapters) and want continuous figure numbering for the whole publication, so I have set up numbering like this: \setupnumbering[satus=start,way=bytext] At the end of the document, I repeated the same images but now in larger format, with captions added etc. I would like to restart their numbering, so the figure-numbers of the large images match the small ones but \startnumbering[state=stop] does not have any effect. Is there any other way of stopping/restarting figure numbering? Thanks a lot, Femke
