Adjustment Brush Pin duplicate pin them invert mask

Is there a way to invert a adjustment brush mask so I can make adjustments to the parts of the image? Such as I make adjustment to the dark areas to reduse noise then duplicat the mask so I can invert it to then sharpen the rest as an example. I know if one adjustment pin that is duplicated sits on top of the other you can not access the one below without moving the top one. Adobe needs to have an option to bring the bottom pin to the top by right click then select bring forward bottom pin. As for the inverting the duplicated mask if this is not possible then Adobe needs to add this option because I would use this many times and I don't think it should be too difficult to do for them to add this in.
