I'd like to be able to display the relative value of my releases across my portfolio so it seems like it would be pretty useful if I could roll the Aha scores of the features into their releases for display in my notebook.
Thank you for the idea. This is currently possible using pivot tables. In fact, there is a great example view that you can customize to get this quite easily. From Reports -> Pivot, click the Views button then Related views. Choose Pivot table: Feature score average by release. When viewing this report, click Select data and change the "Within cells" value from Average to Sum values (see screenshot.)
