Replace Content Controls with text

Hi I am pretty new to WordML and docx4j. I need to do a pretty common thing inject data into word documents before delivering them to the users. I like concept of data bound content controls but I do not want them to be retained in the final (delivered) document but rather just textual (formatted) content based on the injected data (setting content controls to be read/only is not acceptable - the documents will be editorialized after generation).
Is there any way to do it with docx4j or MS word itself (like calling some method to convert controls to text)
