Book POV selection

Adding this idea as Narrative Reporting but please move or let me know to resubmit if it belongs elsewhere.

Would like Reporting books to have a book POV where reports in the book will run for all selected members. In Reporting books there is no concept like this; a concept that Financial Reporting has and many customers used.

When creating a report book and after adding a report, a POV appears at the top of the screen. Selecting multiple members for a dimension in this top POV does not run the report for each selected member. Instead, the report runs for just one member. The POV is acting as a way to filter the member selection but does not produce multiple reports.
