Hierarchal Group Layer Visibility Control

I have two diagrams that want to show a common data model differently. I would like to hide some group nodes, but keep the children (subgraph elements) visible.

I put the group nodes I want to hide into one layer and the children (both groups and nodes) into it’s own layer. When I hide the top group layer it makes all children hidden - even though their layer is still visible. Note: changing opacity has the desired effect (I have control over children separately), just not the visible parameter.

Are there options to make an outer group disappear while keeping the children elements? I prefer to control this via templates without manipulate the data model (e.g. remove items).

Thank you,
Phil

I don’t suggest using visibility for this. Instead, change the opacity of the groups.
