How do I create a new level of approval for requisitions

Summary: We have a requirement to create an additional level of authority in our requisition hierarchy based on value. 

Content (required): We currently have 6 approval levels and the business now wants a new value level put between levels 5 and 6. The six levels have been in place since 2017 when Fusion was implemented. I am looking for information on how to create a new level. It may need setting up in HCM as the link to the approval level is in Job Details - Job Description
