[Seaside] SUInPlaceEditor - can it be made to update a non-local component

[itsme213]

In some of my uses of in-place editor, the same model object also appears 
elsewhere on the page. Is there a way (e.g. magic of #evaluator?) to do this 
somewhere in the inPlaceEditor API?

  html span
    script: (html inPlaceEditor
      triggerInPlaceEditor: [ : value | self model text: value ];
      callback: [ :r | self localReRenderOn: r];
    with: [ self renderTextOn: html]

Thanks - Sophie
