Part configuration for PO of type Supplier Managed

Hello dudes
Does anyone know how to configure a part so that when the PO is generated from the purchase suggestions it is marked as Supplier Managed and NOT standard, or maybe it is necessary to generate a BPM?

How do you control this type of issue?

We do not have any parts that are supplier managed, but we have warehouses and bins that are supplier managed. When we order for supplier managed inventory, we flag the PO as supplier managed, then when the material gets to the warehouse it is received into a supplier managed bin. We can see the parts and quantities in the bin but no cost is added to our inventory until we transfer the parts from the supplier managed bin into our bin. At that time the material is determined to be ours and an entry is created to debit our inventory account and credit our accounts payable clearing.
