"Ideas Origin" - I need to track where my Ideas Users are coming from for Metrics

I have a single Ideas Portal for User Feedback, but I need to determine where they are 'arriving from' - is it my application, yammer, training class, leadership, internal team, internal core team, day-in-the-life session, etc. I need an identifier that tells me for each Idea submitted, what their Origin was.

The only way I know how to do this is to create 8-9 new Ideas Portals manually! Yuck! It will be work, and I have to add SSO to each - big pain working with my identity services team - but at the end of the day worth it. But a LOT of work. (see my previous Big Idea with the Template, Copy or Clone the Static Settings.

But this is a different approach. Can a Single Ideas Portal recognize the User's Origin URL or other identifiable address such that we can imply where the visitor came from? Can Aha use Google Analytics or similar strategy to populate a field on the Idea to indicate the "arrived from" or origin point?

This is in lieu of having to create physically unique Portals /URLs such as (below) - all created manually, all requiring time consuming SSO to set-up. There must be an easier way?!
