Magic Window - output Mask and inverse Mask ?

Hi all
I shot an interview where the background is way to sharp. So I'd apply a background blur (Gauss-Blur).
In order to do so, I tabbed the Magic-Window tab and "markerd" the person in the foreground.
After inverting the mask, I could easily apply a background blur.
But, I'd like to color grade the person in the foreground as well, without affecting the background.
So is there a way my "Node" can output the mask AND the inverse mask ?
