Edit ArcGIS Relationship Classes using GCTE?

Hello,

There is a 2012 post with this title, but no answer.  Can you edit ArcGIS related tables through a feature service in a GCTE web application?  More specifically: if I publish an ArcSDE feature class with an associated relationship class as an ArcGIS Server feature service, can I then edit the related records through GCTE?

Thanks!
