  [x] question about how to use this project

• Summary
  Merchant Defined Data fields when doing a payment capture request don't seem to be supported although there is a readme on how to create the custom fields on the CT payment container

• Other information (e.g. detailed explanation, stack traces, related issues, suggestions how to fix, links for us to have context, eg. StackOverflow, personal fork, etc.)
  I have been looking at this readme document (https://github.com/CyberSource/cybersource-plugins-commercetools/blob/master/docs/Example-Custom-Field.md) which shows how to create custom fields under the CT payment container to be used as MDD fields (merchant defined data). Looking at the code however, it appears the plugin doesn't support reading these MDD fields and forward them to the Cybersource Payment Capture request, see attached image

Can you pls confirm whether MDD fields are supported by the plugin and if yes, what am I missing? If they are not, does the team plan to support these?
