Seal Codex, add and remove photographs from sighting

What Wildbook should this feature be in?
Seal Codex

What would you like to see?
It would be really helpful to be able to remove photographs or add them to sightings.

How would this functionality help you?
For example if there are many individually submitted game camera sightings from one seal on same day, after identifying the seal, it would be possible just to remove all but one sighting and add the best photos to that remaining sighting, instead of removing all and submitting a whole new sighting with best photographs.

Also sometimes there are too many photos, usually from same angle or I would like to add photos from better/missing angle.

This would also help with the problem we have with the older data migrated from Norppagalleria. In Norppagalleria, every seal had to be submitted as an individual sighting, even if they were seen together, multiple animals in one encounter was not an option. Now, if we want to fix those older sightings, it would be easier to add the other seal/seals to one already existing sighting and deleting the other/others, than to delete all and submit a whole new sighting.
