@ronpastore This looks good, but one issue. Since the New Endpoint flow shared the files with the Configure Endpoint, it's not showing the automatically discovered items. In the case of the New Endpoint screen, nothing has been added yet, and as a result, we do want to update it automatically.

That said, that might be a bit confusion. Let me give this some additional thought before we make any adjustments.
