When I'm doing my mass uploads, it's frequently needed to specify not the same object on photo (https://www.wikidata.org/wiki/Property:P180) to all files, but the same "point of shooting" property (https://www.wikidata.org/wiki/Property:P1071). It's useful for groups of photos from observation decks, summits, towers, building roofs and so on. So, please, create a field in image description dialogue where I will able to specify P1071 for every file in batch upload.
