I believe there is a great opportunity to capture on Automation (Rules) within Portfolios. The suggestion would be to allow for Portfolios to be a bit more dynamic in their creation. By this I mean, the ability to add projects based on conditions such as, “all projects within x team” or “projects that x member is owner or collaborator of”
I am sure there are other unique ways to define criteria to set a portfolio. I would be interested to hear what ideas the Community has in this regard!
