How to undo a Performance Document status of canceled

Summary

How do we revert a performance document with a status of cancel

Content

I have two performance review documents that were moved to a status of canceled, but need to be completed.  Is there anyway to undo the canceled status?

I've gone through all the Performance Management admin tasks and I'm only see the action to cancel a document.  Nothing to undo the action.

Thank you,
