"Attributed Channel" Report

[#1]

We currently have the campaign report and the marketing / last touch channel report.

The first one only works for campaigns.

The second one does not take campaign attribution into concern.

We would like to have a report where we can see to which channel the visit / conversion is correctly attributed. Ideally with the ability to group channels hierarchically on different perspectives: Instead of a  the last touch channel the campaign channel should be reported if a campaign is "active".
