Enable 2 collaborating users to upload images to the same individual ID

What Wildbook should this feature be in? ACW / all

What would you like to see?
We’d like to be able to have multiple user IDs, but only those who have established a collaboration in ACW, to be able to upload to the same Marked Individual record via bulk import.

How would this functionality help you?
We have several organizations with multiple users doing uploads. Currently, when uploading historical ID kits, they all have to be uploaded by the same user, otherwise duplicate individuals are created since they’re being uploaded by different user IDs.
This functionality would allow organizations to ‘spread the effort’ of uploads across multiple users and not have to remember and search for which user uploaded which individuals.
This would give us a form of organization-level data sharing at the front end of the Wildbook workflow.

This is related to an earlier support ticket here: Question re: uploading to same ID'd individuals via collaborating user IDs - #2 by jason

Thanks!
