Hey @SkuidUserName ,
It seems like you would have to statically build out the logic to identify that specific price book and map out the static name of that field.
For example: on your opp model, add a UI-only field that uses a case statement that would return the name of that price book. Then add a condition to where you set the price book name on the price book model.
I hope that helps, and let me know if you need me to clarify anything.
