Send an xml document with filename via TN

Hello, I’m new to TN. Is there a TN service that will send an xml document with a filename (e.g. send_payment.xml) to a partner https site? TN service xml:routeXml does not seems to work.
Any help is much appreciated.

The TN delivery services, which you normally do not use directly, do not provide for specifying the filename to be used when sending to the target system. The FTP delivery services use a naming scheme to avoid filename collisions.

Thank you very much for a quick and helpful response.
