How to quote all fields in writing a comma delimited flat file

We’re on WebMethods 10.5 and I have a simple flow service writing out a comma-delimited flat file. The partner wants double quotes around every field in the record. Is there an easy way to set this in the flat file schema/dictionary? I see the quoted release character field but nothing that lets me default all fields to be quoted.

Please let me know if there’s something simple I’m missing.
