Does anyone know if wildcard characters will work when allowing/blocking specific sites using Vista Parental Controls?

Here is the situation: I would like to allow all content from myspace.com to be displayed. However, it seems that each photo on this site has a different URL, something like http://XXXX.ac-images.myspacedn.com, where the XXXX can be anything. Short of entering each URL one-by-one, is there an easier way to allow these to be viewed?
