To the "Network Trace" Network Navigator Tools, suggest add "Find Pipes Referenced by Isolation Valves"
There are use cases for where the user needs to select and edit, delete or report Pipe Elements that are Referenced by Isolation Valve Elements. As per WaterCAD's design, Isolation Valves are not a "true" model element, and instead primarily a visualisation of the Referenced Pipe's Initial Status and somewhat equivalent to the function of the [STATUS] Initial Status override section of EPANet input files.
