Based upon feedback from users of the ArcGIS Utility Network, a new Add-In has been released to enable users to rapidly select features by association in the Attribute Pane. Details are provided in this blog. You can download a copy of this add-in below.
**** Note: Revised Add-in 09/07/2022
We have also created a GP tool to preform selections through associations, you can find those tools in our Utility Data Management Support github repo,
