Hi
You can take a look at fetiyek 's reply in this same thread: Why did cortana support feature change?.
"We have received a ton of feedback that the main scenario people want in Cortana is to retrieve the Cortana report pages they or their analysts have prepared, and ad-hoc questions about data were getting in the way as well as overtriggering for other Cortana scenarios."
You can submit your idea about Cortana integration here.
