I use notebooks to communicate with my clients who are groups of people rather then just one person. They submit ideas, which then are attached to features. Features are attached to master features. Currently when you configure the note book, it will not show the feature/master feature relationship. Additionally, you can only assign "release" once. This makes it difficult to communicate how clients ideas are related to features and master features. Being able to do this easily was the entire point of onboarding a product management tool. During my testing, I did not come across it and assumed since all the data is already recorded in fields (ie relationships, releases) that it would be easy to customize a report like this.
Thank you for your idea. There are different ways to accomplish this depending on the type of view you are looking for. This article provides details on creating a master features-centric roadmap. You can also create a hierarchy report to show the feature > master feature > release relationship. A separate report would need to be created to show the relationship between ideas and features.
