Yeah noticed that right away but it doesn't allow you to use existing keys. Such a fracking downer.
It is possible to edit the XML file directly, so set it up with say 1,2,3,4,5,6,7,8, then edit the XML file. To setup the new FSS stuff, I just copied from the default controls XML file to my custom XML file.
Yes, a pain in the :xse, but better than nothing.
