Can i set redactor configuration based on parent?

Hi i want to use a specific redactor configuration for all files and subfolders within a specific parent.
Is that possible?
I know i can tie the config ID to a template property but the pages within this folder all use different templates that are also used in other folders.
I was hoping to set a TV redactor.configuration_set with @INHERIT on every page and set the ID only on the top parent. But that doesn’t seem to work.
Any ideas
