Approval attribute to distinguish between agreements created through fulfillment vs created manually

Summary:

Agreements are created in 2 ways currently for the customer

Agreements created manually in Purchasing

Agreements created through Enterprise contracts fulfillment process ( Import Blanket Agreements process , Track Purchasing activity process run)

Requirement is to setup different approval options

If agreement is coming through the fulfillment process, it should be auto approved (since all approvals are done at the contract stage)

If the agreement is manually created , it goes to an approval rule

Which approval attribute can be used here .

Does document creation method attribute affect other flows since we have POs' auto generated from requisitions and PO's also imported

Any suggestions on attribute?
