I'll add my request in for this.  Users don't like their My Documents getting cluttered with stuff like this.

Here's another application for this feature... My SC server hosts other applications using both IPv4 and IPv6. I would like to be able to provide specific IPv4 and IPv6 addresses for both the relay and web server to listen on. While I understand I could use the "WebServerAlternateListenUri" parameter to specify and IPv6 address, I am currently using that for port 80 so my users can just enter the server's FQDN and not have to type in "https" in the URL when accessing a support session.
