Add Group By Initiative to the Epics Now, Next, Later roadmap view

Who would benefit?

Leadership funds initiatives and a view of Epics and Features would help to tell the investment progress "story"

What impact would it make?

This view is a big benefit to seeing cross-team, cross-workspace activity supporting the investment (Initiative)

How should it work?

In the Group-by selection, choose Initiatives w/Epic or Initiatives w/Features. The board would operating in same way with 3 columns.

Color coding by workspace option would help, but that is another request.
