Can we associate existing Blanker Purchase Agreement / PO to a new Procurement Contract ?

Summary:

If we have existing BPA / PO (approved and in-flight), and we create a Procurement Contract at a later date, then can we link the in-flight BPA/PO to a contract line ?

I have not seen any documentation that speaks about this or describes how to do this. Any guidance is appreciated.

If there is no standard feature then is there any workaround available ?
