behave-classy : undefined step references

Hi, I'm using PyCharm 2018.3.2 (professional edition), running python 3.6, and have just installed behave-classy that provides a class-based API for behave step implementations.

While I'm now able to define and run class-based steps thru Behave, my Pycharm feature-file indicates that the steps are undefined.  So, I lose the ability to quickly navigate from the feature step to the method step (via Control-B).  Again, the feature scenarios will run fine.

Here's an example of one of the step methods ...

from behave_classy import step_impl_base

# create a base class that will contain the step definitions in its own local registry.
Base = step_impl_base()

class PlanningMaestro(Base):

    @Base.given('I get an initial token')
    def get_token(self):
        # Send an initial GET request to the server to return an XSRF token we'll need to pass with our next/login request.
        response = self.context.the_session.get(str(api_tools.build_url(self.context)))
        api_validation.check_response_status(response, 200)
        self.context.auth_header['X-XSRF-TOKEN'] = self.context.the_session.cookies['XSRF-TOKEN']
        self.context.base_header['X-XSRF-TOKEN'] = self.context.the_session.cookies['XSRF-TOKEN']
    ...

Here's part of the feature file...

Feature: Profile Management

  Background: Setup for each scenario test
    Given I load data for adminuser01 from file User_Data.csv
    And I get an initial token
    And I log on as an admin user
    And I get my personal profile information

  Scenario Outline: Data-source files can be imported into a new profile
    Given I load <profile_test_id> from file Profile_Tests.csv
    And I load data for timedim from file Dimension_Time.csv

---
The feature file indicates that the above steps are undefined references.

Is there a way I can get Pycharm to identify these steps?

Thank you
