Insert the content of a document in a Content Control SDT of another document

Hi,
what is the best way to import the entire content of a word document into a Content Control SDT of another document?

Thanks in advance,
Ernesto.

@ernestocastellano You can use DocumentBuilder.MoveToStructuredDocumentTag method to move cursor inside SDT and then use DocumentBuilder.InsertDocument to insert documents content inside SDT.
