Accessibility Checker - Allow multiple selections

Can you allow multiple items to be selected in the accessibility checker window. I have hundreds of grouped shapes, in multiple slides that do not need to be accessible and it would be much easier to have one click to switch them all off than having to click them one by one.

Also it would be useful to have a 'clear all' accessibility option so the editor can switch on rather than them all be defaulted to on. I can't really see the benefit of things like lines ever needing to be accessible and it takes forever to switch off.
