[Portfolium] Allow me to edit evaluation portfolios after saving

Problem statement:

In the new enhanced Canvas Portfolio (currently in Feature Preview), when I hit Save, a very scary message appears telling me that once I save, I won't be able to add students or edit the portfolio. This is not acceptable and not how the other Canvas features work. Canvas quizzes and assignments etc. allow editing after saving. They show the warning about editing only after at least one student has submitted. And even then, they allow editing for future submissions.

Proposed solution:

Like Canvas quizzes and assignments etc., Canvas Portfolio should allow instructors to edit the Portfolio after saving, at least till at least one student has submitted.
