I've updated my PIE with MultiIE (allows tabbed browsing, etc.) so my menu stucture has changed. However you might be able to go into the settings of PIE and make that change.
You can also use something like SK Tools (
http://s-k-tools.com/). They offer a free, never-expiring demo. With SK Tools you can change the user agent.
If someone who is still running the stock PIE wants to chime in I know that myself and telebiz would appreciate the help.
