Hi John,
Please could you elaborate further on what type of configuration are you looking to change? Usually, the list of properties that can be changed from config tool are mentioned in VP-->Main-->Tab-->Content panels of selected tab-->Other Properties section. Moreover, you can add custom code in 'Render Script' section within 'Advanced' option.
If there are any other configuration that needs to be changed, please let us know.
Thanks,
Team SoftServ
