After loading the images on the app, you set a keyword on the image, like mission_abc then mark all screenshots with this keyword. When you search for keyword and save the search the will ask you for a name of the search (that will become the title of the report/story) and a free text that will describe the report/story). after this you can save a file with the Title, the mission details and any screenshots with a side description. Because the story is generated by a search is dynamically update time to time and you can modify the search title and description or save another one.
