Well… Sort of. Even though it’s limited to the session scope, it could still open a popup on a given page by looping over the pages known to be a part of the session.

See [this solution](https://forum.inductiveautomation.com/t/system-perspective-navigate-doesnt-work-on-session-custom-property-tag-change-script/78348/5) I posted for a similar navigation attempt.

Even with that solution, moving this to some always-present bit of UI is indeed the recommended approach.
