    Ultra Key (Chroma Key) Subtraction of Matte


      Is there any way to "subtract" an area so it does not recieve the Ultra Key matte? 


      Example, I have a sequence which has a static object (a news desk) that has a slight reflection from the green screen spilling onto it.  This object doesn't move within the shot and should never have the chroma key applied to it so I basically want to "remove the matte" from over the object.  What I am asking for is the oposite of a Garbage Matte.


      Thanks in advance,
