Makes total sense @fivetran-joemarkiewicz - I just wasn't quite sure how to go about it!

@raphaelvarieras thanks for making the update! Would you also be able to add a corresponding reference in the README section about changing the identifier variables.

Once that is updated and the CHANGELOG has been updated this should be good to go!
