Is it possible to Sync Task Subfolders in Outlook?

In Microsoft Outlook, I have numerous Task subfolders that I would like to have access to on my Blackberry. For example, I maintain a separate subfolder for each of my managers, my admin. asst., etc.

Currently, when I select Tasks on my Blackberry, it shows all of the tasks included in every subfolder, but it doesn't sort them by subfolder. Everything is just lumped under Tasks. So now I have 300+ tasks listed line by line. It appears that the only way to sort them is to filter by Category, but I don't manage my tasks using Categories.

Is it possible to sync up Outlook Task subfolders to my Blackberry through Blackberry Enterprise Server? If not, is there a 3rd party application that will accomplish this for me? Thanks!
