Folder Properties for Windows Applications Folder

I have Parallels Desktop set up so that my Bootcamp Windows 7 partition is my virtual hard drive. When I boot up my MacBook in Windows, the programs listed in the Start Menu (All Programs) are arranged in folders. However, when I boot up in Mac OS and use Parallels, the Windows 7 Applications folder found on the Mac OS dock does not organize the various software applications into folders. Instead, all of the folders are missing and the contents of all of the folders is grouped together and arranged alphabetically. It makes it difficult to find shortcuts at times. Does anyone know how to organize the Parallels Windows Applications folder on the dock into separate folders by application? Thanks in advance!
