Hello all,
I'm in the process of setting up a new utility network using Esri's Stormwater Foundation, currently testing setup in a personal environment on ArcGIS Pro 3.3.5. I have created the utility network, which for our purposes is currently very simple, only including Stormwater Device point features and Structure Boundary polygon features.
I am trying to achieve an automatic containment association for any newly created BMP Boundary features. All BMP Boundary features should have an associated Stormwater Device point they contain, but not all Stormwater Devices may have a BMP Boundary container (we have many stormwater device features in our dataset that will have their BMP boundaries added later). Essentially when a new BMP Boundary feature is made, I would like it to automatically become a container associated with any Stormwater Device points within its polygon.
I believe I have the appropriate Association Roles and Containment Rules in place for the features in question (shown in the screenshots below from the UN Properties).
UN Association Roles for Structure Boundary features:

UN Containment Rules:

Other documentation/posts have led me to believe that default associations should be able to be configured from the templates for creating features - but when I edit an existing/create a new template there is no option to set containment/association defaults (shown below). I understand that attribute rules are another avenue to trigger association creation for new features, but this method seemed more likely to be a greater challenge given my current arcade skills.
BMP Boundary Template properties:

Thank you for any direction folks can offer!
