IT System Assignment Path

It would be useful to be able to see (in a report, or even better interactively) the assigned categories bottum up and top down.

For example

If I select a business process on Level 1, I want to be able to see which IT systems are used within this business process all the way through the assignment levels (i.e. 1-4). This way I dont have to add the systems manually on the top levels which will result in making human errors, especially with changes.

The other way around: If I select a system, I can now see which process its support (i.e. level 3/4). But it would add value if I could somehow also see to which Business categorie (Level 1) that process is assigned
