Show child initiatives nested under parent initiatives on the strategic roadmap

We have initiatives on workspaces that roll up to other initiatives on workspaces above.

Being able to collapse more than just 1 initiative to the left on a strategy roadmap would enable us to quickly convey a concise picture to C level management and where needed dive deeper into specific initiatives to show how sub initiatives and epics contribute to said initiative and quickly get back to the overal view of main initiatives. This enables you to quickly dive in to specific initiatives for detail and then back to the general overview.

Currently the only options for displaying initiatives and epics are too black and white. Either you have just 1 layer of initiatives with epics. Thus missing the relationship between other sub departments/workspaces.

Or you can create a custom map with all initiatives and epics. But these are not collapsable. So you alway's miss an overview and you alway's get ALL information.

Both currently available options are not tailored to this flow.

So in short. We have this Initiative > Initiative > Epic. (And maybe preferably even more nested initiatives possible)

We would like to have initiatives nested/collapsable to the left and epics in the main view. (Only visible if you expand initiatives) This gives you best of borth worlds. Concise overview. Detail when needed. Fast navigation. All without compromise.

This would be great! We have parent initiatives in our business line, which split into (product-specific) child initiatives, which contain epics.

Take the following hierarchy:

Business Line Initiative
Product 1 initiative
Epic A
Epic B
Product 2 initiative
Epic C
Epic D

Right now if I want to visualize a strategic roadmap for the business line, I will see Business Line Initiative but that won't show the child initiatives or their epics. Note that this type of visualization is extremely useful to visualize dependencies across products/teams, and in general which work is being done across the org for a specific effort.

The only way for me to do that is to have Epics A-D all linked to the Parent Initiative, but still under their respective product workspaces, and delete the child initiatives. This is fine conceptually - however, it creates another problem: When I want to generate a strategic roadmap for Product 1, I can include initiatives from Business Line, including Business Line Initiative. This will show me (correctly), Epics A & B under that initiative, but will also show Epics C & D, which are underlated to Product 1. Note that, at this time, there seems to be no way to filter out epics by workspace in the strategic roadmap. ( This latter is probably another idea )While this is somewhat possible by building a custom roadmap, all the nice visualizations of hierarchical relationships, and the ability to edit timelines on the fly are lost.

Solving either of the issues highlighted above would be a huge help for organizations with larger product portfolios!

Our product managers are using Aha in Scaled Agile Framework mode so Initiatives map to Epics and it is usual to have parent and child epic relationships, hence the requirement.
