Hi Mike,
I am disappointed with this response. I know that only one folder is supported. What I was trying to get was whether it WILL be supported in 10.2.
This feature forces people to workaround the structure of AGOL/Portal and clutter the entire Catalogue. And when Esri finally supports it (without telling in advance as it is happening for the last years) people will be forced to readjust their client apps and services to fit into the appropriate schema undoing the workarounds.
Kind regards,
Jose
