Johannes has been a developer with Funnel since 2016.
By popular demand we've introduced the ability to add data source name as a suffix to field names when using Google Data Studio views.
This option was available before, in an earlier version of our Data Studio connector. We figured it'd be unnecessary with the introduction of "views" – but we were wrong – so now it's back!
The option is controlled per-view and in Funnel rather than per-connection and in Data Studio (as in the earlier version).
