It would be awesome if there was a way to share content publicly for a set length of time, without having to go back and manually unshare it.
Concept: After selecting the Everyone (public) option, it gave you a choice between indefinite sharing or providing a date range for changing the sharing temporarily. Then after the date range ends, the item reverts back to the last sharing setting. Similar to the Survey Status option available in Survey123, but for other apps.
