Accessibility workflow improvements

I just submitted the following feature enhancement/request: 

Accessibility options (alt text and object visibility) for shapes, images, and video should be available from the format shape/image/video dialog without the need for an extra right-click menu item selection.

Likewise, just as I can add alt text to images/video in the Media Library, I should also be able to set object visibility for accessibility tools as well.

Currently the workflow for accessibility is overly cumbersome, and allowing me to manage accessibility features from the Media Library and format dialogs would be a huge efficiency gain for my workflow.
