How to remove 'data tip' related menu items from Debug menu?

Hi,

I'm using the VS 2010 isolated shell.  I'm trying to remove the various data tip related menu items (Clear All DataTips, Export DataTips..., Import DataTips...) from the Debug menu.

I see no option in the .vsct file to do so.  Is there a line(s) in .vsct  file or is there something else that needs to be done?

Thanks,

Notre
