Story

As a Product Manager, I want to be able to filter by Initiative or Epic, in order to help frame discussion and presentation when diving into Epic and Story view.

Expansion

As my team get's deeper into Portfolio, we have multiple Product Mangers interacting with the same Plan. While we can drive high-level engagement using the Portfolio plan, it becomes a less useful when I want to focus on a specific Initiative, it's components or deliverables, as I can't provide a specific view.

This is especially obvious when I have more than one project which contributes to the same Initiative, and I'm engaging in focused project reviews with stakeholders.
