If the page option is not available in the "Use Facebook Page as" list (from the Account menu), then you are not an admin.
If you do see the option try switching and using Facebook as a page. If this does not work you may want to file an appropriate support request via Facebook Help : Pages for Business.
I have tried to use Yahoo Pipes to do this...but I didn't do it right...I assume one could accomplish this by creating a combined feed and importing THAT feed in to your notes section.
I do not know how to do that though. but I am sure it is possible this way.
