how to duplicate a set of portal records?

[Andrew5]

Database has a parent client records table and a child client billing table in a portal with a 1 to many relationship. Duplicating the client parent record is easy, but I would like to duplicate his portal billing records to create a second set of billing records for his second entry in the parent client file, in order to save a lot of typing. Any way to do this?
