P: (Masking) Selecting multiple objects using the masking tool

The Object select is a great addition to the masking tool. However, it is very frustrating not to be able to select multiple objects in order to apply the same fixes using the masking tool. I have a tricky photo in which I have had to tediously select each object, at least 20 of them, individually. It would be helpful to be able to Cmd-select for multiple objects.
