You could configure a workflow template to export items using PIE-export-to-plmxmlfile handler.
individual xml files can be achieved by launching 1 sub-process per workflow (parent process) target item.
I figured out how to export single items using workflows, but when TC creates the item, it creates as .plmxml not .xml as I expected. Also, as I didn't specified the argument -file, it saves the file in TC_TMP_DIR, which I had to change in systems variables to save to the directory I want. Is there a way that I can specify the argument -file on the PIE-export-plmxmlfile to something like \\dir\ "item_id".xml?
