Now, Next Later roadmap definable by status

What is the challenge?

Now, Next, Later roadmaps are driven only by dating fields.

We would like the ability to define not just by dates, but by epic status as well.

What is the impact?

The impact is that for us, the most effective NNL roadmap would be as described below.

Describe your idea

We'd like for column one to be our Done and Shipped items, with the middle column being our committed to release items, and the third column would be our being prioritized and on roadmap items. Then we can filter by dates so we're not pulling in done and shipped items from years ago.
