In the bootcamp-presentation the following slide was shown. I understand how it is possible to filter (query) on username in survey123.
But is there any possible way to assign a pointfeature to an user in AGOL? It would be a great thing to edit a feature in a webmap and choose users in a dropdown-list and voilá they appear in survey123 or shown in collector. Or is the only solution to spell the username correct in a text-field?
