Did you manage to figure this out? I am creating a hierarchy, and use a related field to choose the parent, so thats all OK, but I am trying to work out how to create the path/slug based on the parent/child hierarchy. I wondered if your issue was similar and could help. At the moment we enter the full path as the slug, but ideally we want build the path based on combining slugs of parent/child entries. My post is here Anyway to auto create slug hierarchy based on relations? Parent/Child
