On Windows 7, is it possible to configure an additional static IPv6 address in addition to a dynamic IPv6 address?

http://serverfault.com – I have a Windows 7 box that already has a dynamic address assigned by a router but I would like to add a static address (private/Unique Local - not a link local). I don't see anyway of doing this via the UI unless I turn off dynamic address assignment. Is it possible via the CLI? EDIT: And how do I make it permanent? (HowTos)
