How to append a semicolon at the end of each line

We are exporting a table to csv which works fine. The fields are separated with semi-colons. All fields have double-quotes around them. However we would like each line (record) to end with a semi-colon. Is there an easy(morph) way to accomplish this? I could not find a solution in the help files.

Re-import the file as text (no headers, no delimiters, ignore quoting), append a semicolon at the end using an expression, then export again ( no headers, no delimiters, ignore quoting). Note that you can insert the import action at any point of a workflow.
