Ability to convert Predefined Choice List to Predefined Tags Field

Sometimes a custom field type needs to change to meet evolving reporting needs.

In the current config a resource would need to create a new custom field and populate values to the new field. Which can take time and introduces human error (even if bulk updating).

I'd like the ability to convert a Predefined Choice List which is a single-select field to a Predefined Tag Field (multi-select). The movement in this direction makes sense bcs a user would have only populated 1 value. Converting (rather than creating new and populating) would remove the human error. New values can be added after the conversion.
