Purchase Order Treatment

I have created a Material Request and then on the basis of Material Request, I have created a
Supplier Quotation and then on the basis of Supplier Quotation, I have created a
Purchase Order
Now, the problem is, I noticed that, I have wrongly selected the Supplier in the supplier quotation therefore the same is coming in the PO.
Now, I need to change the Supplier in Supplier Quotation as well as PO, what is the best solution for the same.

Note: PO is in just draft stage, therefore neither we can cancel and nor we can stop the PO. Same is with Supplier quotation, as the quotation is linked with the Purchase Order therefore you cannot cancel it.

Just make a new Supplier Quotation?
