Can we leverage contract approvals in Supplier Contracts Mgmt (SCM) to bypass requisition approvals

Currently, we are utilizing approval workflow for contracts routed through Supplier Contracts Management (SCM) and also for the related "special request" requisitions created in ePro which we are linking to the associated contract. We'd like to eliminate the requisition approvals (as the approvers tend to be the same ones as on the contract) and capture all the required approvals in the SCM approval workflow. Is there a way to bypass the req approvals for "Special Request" reqs only without changing any code? Can it be done by setting up process definitions on the "Approval Process Setup" page?
