The ability to vary the Separator Text field in the Formats.xml file, but on an RRD level, would allow for export to multiple different CSV types (for example many of the destinations require Pipe delimited, to avoid commas in fields which corrupt the data)
Currently, if we have the default as a pipe, but someone wants comma delimited, we have to create a formula field within the report which concatenates the data fields and creates the separators.
Ideally, you would be able to create new export profiles within Formats.xml and these could be added to the options in Solution Builder... that would allow for a little restriction when junior users are setting up tasks.
