I created a new workflow where tickets started life in a status called "To Do" which I didn't realize was being used in other workflows for other projects.
Then I changed the status to "To Review" not realizing it would change for other projects.
Then I activated the workflow for the other project.
Now I can't change the name of the step back to "To Do" because that status is already used.
How do I change the "To Review" status back to "To Do" (i.e. how do I reuse an existing status? Reusing an existing status doesn't seem available when editing a workflow status, only when adding one to a workflow)
