Batch adding annotations?

I’d like to be able to batch edit annotations at least for my own observations. I know these photos reasonably well, and choose only the ones obviously in flower when working from thumbnails. I’ve tried doing this through My Observations but the system returns 8 records where there should be many hundred. I’ve tried fooling with the url, but so far no luck - it stubbornly returns all my obs.

Here’s what I tried:
