title: How to backup the custom policies automatically
body: <p>When we're using the developer tool 'AAD B2C Custom Policy Manager' to do development work, all policies that we published there (production and development) are all listed in one place. And it's possible (unfortunately it happened) to click on the 'Delete App Policies' button by accident and all policies are gone. Then the whole authentication process is broken. Is there anyway we can backup the policies and restore them online? I know we can do this manually, just I'm wondering if there's a better/standard way to do it. Thanks.</p>
