Strategic roadmap format for custom roadmaps

It would be great to be able to build a custom roadmap with any record type using the 'strategic roadmap' framework/design. It looks presentable, it's easy to understand, and has useful features like re-organising record timelines, expandable sections and so on.

There are a few roadmaps that follow the same format (e.g. the releases gantt) but the custom roadmaps are not as nice to use and generally have poorer UX. It would be great if we could create a roadmap view with the flexibility of the custom roadmaps but with the visual elements of the strategic roadmap.
