CSV export for Capacity Report

One of the most useful reports in Portfolio is the capacity report.  This is shareable via a link, but none of the raw data, booked, unbooked, utilisation and constraints etc that is available in the clickable popup  for each bar is visible.  

I would really like this information, in order to produce a capacity planning report for the Executive Board.  Please make this information available in a csv/excel export like the scope report.

One other suggestions that I think have already been raised. filter and group by stage so I can see how much capacity is available in test VS development stages.  

Expose portfolio data via the API's  so we can extract this data
