Is there a way to make the object and other masks have continuity like a brush?

When creating a mak and using the add or subtract with the brush tool there is no need to keep selecting the brush when you want to brush over multiple areas of the image. If I do this with the object tool I need to select an object, then hit add again, choose object and select the next portion. This is an incredible waste of time. The object tool often is faster and has better precision. 

Come to think og it, the add or subtract should be sticky until you turn it off. I am pretty sure I am missing something here and it is just an issue of me not knowing how to get this to work in such a way.
