Let’s say that I’m trying to create a pod named book, and I want to add the chapters it has. However, I don’t want to go into my "chapter" Pod, and create a new chapter, and then add it to my Pod. I want to be able to create a book and then click on "add a chapter" and add the name of the chapter and the number of pages it has from inside the book pod, and obviously attach it to the book pod. Is this possible? Can this be done with an input helper?
