Maintain cycle time data when team workflow is changed

Currently if I select a new workflow for my team and map my statuses to new statuses, I lose all past cycle time data because cycle time only focuses on the current workflow being used.

Instead, I would like to see historical data that coincides with my new workflow. Based on how I mapped my statuses to this new workflow, I would like this status history to be preserved in my new workflow as well so I can still access this past cycle time data.
