Dear McBr0wn,
Thanks for your updates.
Based on your scenario in your environment, you may use different formula to create the relationship.
Generally, you may deploy the cascading drop-down list to simulate the relationship scenario in PowerApps.
Create a dependent drop-down list in a canvas app - Power Apps | Microsoft Learn
So please upload some related screenshots of the app you have created and provide some examples about the relationship you want to create for our reference and we can see if there are some formulas meeting your requirements.
Thanks for your effort and time.
Sincerely
