Can you transfer the liability (open payables) from one supplier to another?

Hi!

Is there a workaround where we can transfer the liability (Open A/P created in PO) from one supplier to another? For example, we have created a PO for supplier ABC but the payment will be done thru supplier DEF as part of our contract. So the process is that we are paying supplier DEF via Post Date Checks then they will be the one paying supplier ABC, we can just create a PO for supplier DEF to solve our problems but supplier ABC requires that we provide them a PO form under our name not from supplier DEF.
