Would you be able to share the segment you've used for your audience creation? Are you storing the userType in a persisted variable like an eVar?Its very likely there is a work around for this based on how you create the segment.

You need to set up an integration in Adobe.io.  You can do this if you are an admin.These are two pretty good videos on getting going.Using Analysis Workspace to Build API 2.0 Requests​ Using Postman to Make Adobe Analytics 2.0 API Requests - YouTube

Analysis Workspace is limited to 400 rows per freeform table; the api 2.0 is not limited to 400 rows per request. Further more if you are using an api you automate the process to say grab rows 1-50k, then 50001 to 100k etc.The large advantage of an API is that it will allow you to address this progr...

Would you be able to confirm the persistence and allocation settings for your eVar?  That would dictate the validity of your segment.Conversion Variables (eVar) If the persistence is visit and allocation is most recent, then yes your segment should work.  If persistence is hit then it would not work...

If you use 'Most Recent' allocation, with 'visit' persistence  you'd be able to achieve this, so long as you always set the eVar at the same time as the custom event. In your sample above it would be of trivial effort to pass the pageName into an eVar to achieve that.Conversion Variables (eVar)

What about using API 2.0?  I'd imagine it is an option as it powers analysis workspace.

Greetings, If you read further down in the same help doc you will find an explanation of the difference.How does Average Time Spent on Site differ from Time Spent per Visit ?The difference is the denominator in the metric:Average Time Spent on Site uses the sequences that include a dimension item.Ti...

In the example you provided above, organic would be the last touch channel for page y (assuming you enable organic to override paid).  Its the last channel set prior to seeing page y.If you use a 'hit level segment', the view of 'page y' would only be attributed to organic.If you instead used a 'vis...
