django-fsm: dynamically-generated value based upon model instance in the custom properties for transition decorator

Question

I'm incorporating django-fsm into a Django project containing a model that will include a number of state transitions, like so:

from django_fsm import FSMField, transition


class Record(models.Model):
    state = FSMField(default='new')

    @transition(
       field=state,
       source=['new', 'flagged'],
       target='curated',
       custom=dict(
           verbose="Curate as trustworthy",
           explanation=("This record is deemed trustworthy."),
           url_path="curate/",
           #url_path=reverse("record-curate", kwargs={"pk": self.pk}),
        ),
    )
    def curate(self, by=None, description=None):
        """This record is deemed trustworthy.
        """
        return

    def get_curate_url(self):
        return reverse("record-curate", kwargs={"pk": self.pk})

I am now at the point of wanting to connect up some views to activate transition changes for an instance of Record. In the example above, url_path is a hardcoded path to the view whereas I would like to dynamically generate the path value based upon the pk attribute of the parent Record instance. I understand that I can't access self within the decorator, but is there any way for me to get access to an attribute value of the class instance of the decorated curate method?
