Custom page view names for SPAs

When I use the plugin as documented for a React SPA with router v6, the name for all page views is the page title ("React App" by default). This makes it difficult to track user progress through the application. I was able to solve this using the following telemetry initializer but this doesn't seem very elegant.

appInsights.addTelemetryInitializer((env) => { if(env.baseType === "PageviewData" || env.baseType === "PageviewPerformanceData") { env.baseData.name = window.location.pathname; } });

It would be great for developers to be able to specify how to obtain the page name rather than having to modify it after the fact with a telemetry initializer. Alternatively, if the above approach is the recommended method, adding it to the official documentation would be helpful.

Start by tracing how the React plugin creates PageviewData and PageviewPerformanceData for SPA navigation, then compare that path with the telemetry initializer shown in the issue. Done means either a supported way to derive custom page-view names is available or the recommended initializer approach is documented.
