Usage Blades (Users, Sessions, Events, etc., etc.) usable across App Insights Resources
Even though I can create Analytics queries across multiple AI resources, I do not have a way to view information across AI resources in a view like the blades in the Usage section. I would really, really like to be able to use these blades across AI resources, not unlike the way that the Transaction view automatically spans AI resources when looking at telemetry.
Our system is composed of 30+ different ASP.NET applications and one SaaS non-.NET site that users interact with as if it were a single system. We have all pieces of it instrumented with App Insights, each with its own resource. (We originally tried having all telemetry going to a single shared bucket, which turned out to be very unhelpful for most application teams.) But we can't use some of App Insights' coolest features since the events and page views span many applications.

Thanks for the valid suggestion. Your feedback is now open for the user community to upvote which allows us to effectively prioritize your request against our existing feature backlog and also gives us insight into the potential impact of implementing the suggested feature
