Select a specific photo in lists

On your life list, you have the ability to toggle between displaying the default taxon photo or photos from your latest observation of that species. I prefer showing the photos from my observations, however the photos of course greatly vary in quality. I think adding a way to choose which observations photo you would like to appear would improve the life list feature. I would rather display a great picture of a species that I took a year ago than a blurry photo that I took yesterday.
