I seem to remember that Cascade Story Map Builder did this. It provided a little notification icon for content that didn't have alternative text, etc. It would be nice to see something like this for StoryMaps. Maybe like a red dot on the Publish button (like Survey123 does) and then when you clicked it, the drop down menu has an item to zoom to or list the content pieces that are missing the alternative text. It doesn't have to prevent from publishing or anything. This would help us as an local government organization appease our policy, analysis, and communications department when encouraging the use of StoryMaps. It would also help me as a creator when I've added a bunch of content blocks and have to go through one by one and make sure I've added alternative text everywhere.
