You can use bean shell scripts to execute code that can manipulate CSV files. This question has an example how to change data in a CSV-file. You should be able to adapt it to adding data aswell.

JMeter is a load testing tool not a CSV manupilation tool. Use other tools to prepare your data. There are a lot of commandline tools you can use to do this, which you could call from within JMeter.

A example flow:

  • Initial testdata in prepped in a CVS-file
  • JMeter collects data in a file
  • Commandline/BeanShell script combines JMeter data with other data into file Y
  • JMeter uses new file Y todo something
  • More reporting

Your question is not detailed enough to really give a good examle, but hopefully this triggers you to come to a solution for your challenge.
