Export scene property values to DUF

Is there any native support in the scripting environment to generate DUF files from a scene in DAZ?    I need to export a specific set of properties values to a DUF file.   I can certainly do this using the built-in support asset saving tools, but I need to programatically specify what goes into the DUF file.    I don't see this anywhere in the API docs, and I'd certainly like to avoid writing my own DUF file writer if possible.  

Also, unrelated -- is it possible for a DUF file to trigger a script execution when it is applied to a scene?   And vice versa -- from a Daz Script, can I apply a DUF file to a scene node?

Thanks
