Need to configure the ApproveAdjustment workflow in BPM for "Transfer" and "Split and transfer"

Summary:

In our implementation, Departments are configured as project-owning organizations. We have a requirement to configure the ApproveAdjustment workflow in BPM so that for both "Transfer" and "Split and Transfer" actions the approvals are routed to the cost center manager for the project-owning organization, i.e. the organization manager as shown in Manage Departments. Of course, if the cost center manager is not populated then we have to route the approval elsewhere, but the primary challenge is to identify the cost centre manager and route the initial approval to them.

Has anyone done this successfully, or done anything similar that may help us meet our requirement?
