When adding a new story to to a map tour or map explorer, it would be great to be able to link to another storymap in the media box and have a photo pop up (such as the photo chosen as the thumbnail to the existing storymap). We have storymaps about really cool things our agency is doing, but there's no way to profile it in a storymap tour/explorer. Currently, we can only add an image or link to a video. When making a regular storymap, it's possible to embed another storymap. That's exactly what I want in a storymap tour or explorer.
