Can you view containers and contents in ExB? For example - Strands within a Fibre cable

Just wondering if view containers and contents can be viewed in ExB? example - Strands within a Fibre cable.

Can you pick a strand and trace it using the trace widget? I am tinkering around with the communications foundation solution supplied by ESRI but I couldn't find any information around my question.

Thanks.

Only widget available right now is the View associations one in JavaScript SDK, but doesn't cover containment associations  UtilityNetworkAssociations | API Reference | ArcGIS Maps SDK for JavaScript 4.28 | ArcGIS Developers
