This question seems to have been asked several times for a few years now, but I don't see any real answers. I am hoping by now there might be an answer.
Q: How do I get User Story Points rolled up to the Feature level in the Plan Est column? I am trying to get this view when in the Portfolio -> Feature menu path.
The field that you're after in any list view (like Portfolio >> Portfolio Items >> Feature) is the Leaf Story Plan Estimate Total (oddly it's not available in card views) or you can get it on the User Stories tab from the Feature editable detail page. Hope that helps.
