collapsed group to show not only label, but icon or diagram

[tetemes]

I would like to be able to see not only text but selected element(s) from the group when collapsing a group.

I can create a group of a box with selecting the box and clicking Arrange/Group menu then I am able to place items inside this group and collapse/expand on demand.

Currently:
Only the label of the box is shown when the box is collapsed.

Request:
I would like the collapsed group to display not only the box's text label, but also an icon with its text when the group is collapsed (auto-sizing/manual-sizing), so that I can make the group visually more understandable. Once this capability is available, I would be able to create expandable/collapsible architecture diagrams.

Nice addition:
If it was possible to have a switch to expand/collapse everything in the same level (groups could be selected to be in the same level), where I can switch between context, container, component and code level of details from the C4 architecture diagram model, that would complete the feature nicely. This was I would not draw so many separate diagrams with different detail levels, but would be able to maintain a single diagram and it would contain details of multiple levels.

Thank you

I just thought about the exact same thing while experimenting with the C4 model earlier today.

Our current workaround is to create multiple pages for context, containers and components and then simply place a link on the Containers or Software Systems boxes. Works like a charm with the diagram viewer, except for navigating back (so we're simply added backlinks manually to the diagram titles, to be able to go up in the hierarchy again).

I believe my stackoverflow question (below) is a request for essentially the same feature. I have included sample images for the behaviour I would like to see.
