Power BI JS API Event Listeners - saveAsTriggered and saved

I'm trying to create possibility for Web App users to Edit and Save Copy of report.

I can track Save and SaveAs events only at saved event. To determine type of the action I need to compare Ids from customEvent detail (for SaveAs event.detail.originalReportObjectId defined, for Save - not).

My questions:

1. Is there any other possibility to determine saving type?
2. Is there any possibility to see the actual report name (for now event.detail.reportName is empty)?
3. When does saveAsTriggered event fire?
