Email “Bubble UP” feature in 2002

If I have 100+ sub-folders in Outlook 2000 or 2002 and use the rules wizard to move incoming email to these folders, is it possible to have the new email bold up from the sub-folder to the main folder. Example – Main Folder called Microsoft – Office 2000 – Issues. If I have an email moved when it arrives to the Issues folder and the Microsoft folder is not expanded how can I setup my folders to show me that I have new email in the Microsoft folder?
