Currently, when designing the workflow for a Tracker allows the standard and custom field status to be set as either "normal" (blank selection), "read-only" or "required". Could we please have another option added as "clear" or "reset"?

The logic behind this request is having the ability to clear certain issue fields when a specific issue status is set. For example, setting the "Target Version" field to "Clear" when an issue gets a status of "Rejected" would remove a rejected issue from whatever Roadmap it was previously assigned to.
