Has anyone setup career progression train based on positions?

Summary:

Looking to setup career progression based on positions, but can only see career progression based on Jobs

I have setup job progressions, job profiles, position profiles and career paths. The train for career path is still based on Jobs and not on positions. Has anyone see the career path progression base on positions? We are a position heavy company and looking to see if we can leverage the train to show by positions. We are on 26a still and I know 26B has better updates, wondering if anyone setup based on positions.
