Flickr enhancement feedback: batch operations from Organizr's map view

For example, I've just uploaded a batch of ~200 photos from my honeymoon in Paris five years ago. Over the years, the file names got messed with, the photo sequence got a bit messed up, and I don't quite remember now what all these things were or, more importantly, where they were. So I start with the Map view, placing the places I can remember on the map and doing some digging to try to figure out where the rest might have been, and for the most part this works well. But now I've got a big batch of photos, and I want to be able to say "all of these were of Versailles, while all of those were of the Eiffel Tower, and all of *those* were of Notre Dame. Ideally, I'd just be able to draw a square on the map (same UI as adding notes to an photo), but I could also just zoom out enough for the pins to merge, then select a pin. From there, I want to be able to add tags to the batch of all photos taken at that selected location, &/or do similar batch operations -- adjust the geoprivacy settings to all of them, batch-change the date, etc.
