There is a need to link custom fields with approval processes. I have created a custom field called approvers (essentially a list of people). I want to link my approval processes with my custom fields so when a client submits a ticket they can choose an approver and the ticket is then sent to them for approval. I believe you can do something similar with CABs and Location Approvers but it sends the approval to multiple people not the one approver the client would want it to go to.
