Restoring Island from Published Island

So I have a published island and then I was working on it and forgot to duplicate it. Can I get it back the published version somehow?

@despicableGLEE Thank you for your feedback. While I cannot guarantee a response, I can confirm that this has been forwarded to the appropriate team.

The docs are here

Heres a youtube vid on it
