Hi Ulises,

You can use the SignatureWidgetAnnotation.sign API to sign multiple signature widgets. Together with annotationManager.getAnnotationCopy you can use the same annotation to sign all the widgets.

Ex:

const signatureAnnot = annotationManager.getAnnotationsList().filter(annot => annot instanceof Annotations.StampAnnotation || annot instanceof Annotations.FreeHandAnnotation)[0];
annotationManager.getAnnotationsList()
  .filter(annot => annot instanceof Annotations.SignatureWidgetAnnotation)
  .forEach(annot => {
    const annotCopy = annotationManager.getAnnotationCopy(signatureAnnot);
    annotationManager.addAnnotation(annotCopy);
    annot.sign(annotCopy);
  });

Replace signature annotation with the FreeHand/StampAnnotation from your code.
