Currently particular search results can be discarded before exporting. Why not have it the other way too i.e. add particular search results to a list before exporting? It would be even more amazing if one could create multiple lists and add a search result to a particular list.
A similar but slightly different feature is being able to mark a search result as favorite i.e. save an individual result to a generic list of Favorites - to be able to (re)view it later.
Both features in app of course.
