Is it possible for DC Plugins to add information to support zips?

Is it possible for DC Plugins (for Confluence, Bitbucket, or JIra) to add structured information to customer generated support zips? I am imaging a scenario where the existing support zip mechanism has an API of some kind that one of my plugin’s classes can implement, or similar, which results in us being able to put some kind of structured data into a new file in the support zip, or added to application.xml, or something else.
