Custom Credit Memo Approval Workflow

There is a seeded Credit Memo Approval Workflow. From a testing perspective, we've modified the seeded workflow in test environment. Going forward, if we want to migrate to production, we do not want to modify the seeded WF. We want to copy the seeded workflow, make modifications as per business requirements, and then USE that workflow for business transactions.   So.. the seeded workflow is not broken. we just want to copy the existing and create our own. The questions is... where do we tell Oracle to use our newly created workflow?
