Hi MRB,
We appreciate that you posted back and confirmed the situation with us.
For your original question about how to overwrite pivot table conditional format based on a specific row label text, as Chitrahaas mentioned above, the formatting of the cell will be blank and if both conditions are true, so we’re afraid that there is no out of box way to achieve your requirement directly.
However, we found VBA code may achieve your requirement. We will help you move this thread to related category, and engineers in related team will try their best to help you.
Thank you for your understanding!
Best Regards,
Sukie
