I agree there should be an easier way. IF a report is being shared, it
should be the exact report (segment / filters / metrics). This would
make QA reports easier. But the sharing of the URL itself will not be
possible as they use this for serialzing the session. If this was
updated to have the session done through cookies, then it would be
possible. But with the shared link, making any changes issue, I have
raised this as a bug in Client Care.
