Since the post is little old, you might have already found an anwer by yourself, but just in case and just for the other readers.
Please check the sample code in the following folder of the SDK ZIP.
It contains some sample AAs regarding to generating of scoping reports in some file format.
You can find the installer ZIP for those sample AAs as well.
And to answer to your question literally, as the above samples show, there is no easy single method call for genrating CSV files.
However, I believe those sample can provide ideas for you to implement any further functionality by yourself.
