Hi Erin,
You might get a lot of opinions on this one. On one hand, if the only business requirement you were trying to meet was to change what your entity was called, you can easily do that in the configuration by changing the entity label.
But if you had requirements to treat these separately you might want to think of breaking these into separate entities, perhaps all inheriting from a hidden (abstract) entity that has the core attribution shared between these entity types.
And of course your requirements might be on the continuum between these two. My advice is that if you are truly having business pain because of the way this was set up, you discuss this with your CSM or a consulting partner.
