Filtering Favorites in Outlook 2010

Hi,

I want to apply date filters to my favorites in Outlook 2010 however when I create a filter say for example on or after 01/01/2012 it only applies to that folder and not any of the sub folders, is there a way applying these filters to the sub folders I dont want to have to go through each sub folder and apply a seperate filter it isn't sustainable for future growth.

thanks.
