Cross Visit Marketing Channels

[#1]

For the marketing channels it would be great to see a cross visit pathing report to see which marketing channels users use and in which order.  It's great to have first and last touch, but the multi-touch would be even better.  I know this is possible with JavaScript (specifically the crossVisitParticipation and channelManager), but it would be so much more effective to easily update via the web interface, not have to manage both the logic in the admin and the JavaScript code
