[Release Planner]: Need doc on how people could update the release planner on the wrong input.

There are certain cases that people have the wrong input for the release planner.
Some of them could be recovered easily by updating some fields directly while other may requires create a new release planner. (e.g. use a new API version, switch the release for GA/Preview)

Today, we don't have document to describe what actions service team could take to recover from the wrong input. So it would be helpful if release planner could have doc on this.
