Create a CSV with a header row in Workflow

I am creating a CSV file in my workflow that lists details of each file processed. I now need to submit that CSV to a department that requires a header row. Is there a way to create a static header row with Create File or do I have to bring my CSV file into Designer to add a header row?

Thanks
Justin

In Workflow, use the Add/Remove Text task. It allows you to prepend or append text to any data file.
Set the Position parameter to Beginning of job file and in the Lines field, type something like:
"MyColumns1","MyColumn2", "MyColumn3"
Make sure you enclose each column title inside double quotes, and separate them using the same separator that you have for the rest of the file.

Thanks Phil, that is pretty straightforward and easier than I thought - I was overthinking it.
