I'd like to use JIRA portfolio to directly communicate the roadmap to various stakeholders. For that a few elements are missing, and I'd be happy to have them:
Changes to reporting views
Defining / using preset reports
Thanks

It may not be the simplest thing to do, but you could consider creating a custom PDF template for the Better PDF Exporter.
As the app integrates with Portfolio, nothing stops you from creating the exact report that you need then share the resulted PDF document with your stakeholders.
Here is a short video that demonstrates how the default template exports Portfolio data: https://www.youtube.com/watch?v=qEqRikB5jTQ&feature=youtu.be&autoplay=1
(Discl.: it's a paid app and I'm a developer working on it.)
