Hi AZBob,
Thank you for posting your query in our community.
Per your description, my understanding is that you want to create a column named "Friendly Description", when the Name column change, the "Friendly Description" can be changed.
Based on my experience, a flow may could meet your requirement, like below picture:
So we suggest you could also post your query in Microsoft Power Automate Community to see if the members and engineers in this community could help you create a flow for your requirement.
Appreciate your cooperation.
Best regards,
Jazlyn
