Forcing NER to ignore stopwords

This is great - thank you Ines! The annotating is already so much faster without including these obvious rejections. As suggested on exit I assign those examples as reject however I am a little uncertain on how to save these back to my data set. The relevant part of my recipe is

    def reject_stopwords(removed_examples):
        for eg in removed_examples:
            eg['answer'] = 'reject'
            print (eg)


def on_exit(ctrl):
    nonlocal removed_examples
    # this is called when you exit the Prodigy server
    dataset_name = ctrl.dataset
    database = ctrl.db
    # do something here
    reject_stopwords(removed_examples)

I am not sure if I should make the updated rejected examples into a list and pass that back or if I can update the dataset on the fly?

Thanks.
