If the delimiters aren't actually needed in CaseComplete, and are only necessary for the system(s) external to your project, you could add the delimiters to your custom report instead. For example:
$repeatDictionarySortName
-~$Name~-
$endrepeatDictionary
...would give you an output like:
-~Account Holder~-
-~Co-signer~-
-~Credit Score~-
...and so forth. I'm not sure if this is exactly what you're looking for, but could be an option for you.
