I complained about this very issue to Wolfram technical support back
in version 6.0.  As far as I can tell, nothing has been done about it.
 Of course, it's fairly easy to implement on your own but, then, it
should be very easy for Wolfram to get it to work as advertised.  It
would also be quite convenient, particularly with the proliferation of
Graphics primitives.
