Accessibility drop-down option that lets you import Slide Notes, I am doing this slide-by-slide. Is there way to apply this action to the whole presentation?

I am adding the Accessibility feature that is in the drop-down menu next to the Slide Title in the Properties tab.  There are 2 menu items there: Tab Order & Accessibility.  When I choose Accessibility, I can import Slide Notes.

Right now I can only figure out how to do this action slide-by-slide (meaning I'm going in to each slide and choosing that drop down option, then clicking on the next slide and doing it again, over and over).  Is there a way to get this to apply to the all of the slides at once instead?

Thank you
