Link purchase order (with contract) - document type

Hi experts,

I need to restrict the link between purchase order type and a contract type.

The creation of a specific purchase order type with reference for a specific contract type, for example, if I create a Contract type MK, I can only create purchase order type NB with reference to that contract.

I know that we have the standard configuration to restrict the link between contract and purchase requisition and from a purchase requisition with a purchase order, is there any standard configuration between Purchase Order and Contract?

Thank you in advance for your help.

Regards,
