Hi,
I fully understand what your requirement is, and this can be achieved pretty simple in code. For the standard flow. In it simplest form you can manually change the purchase order number to be what ever you want it to be after the PO is created.
The thing is that i would not recommend that you implement such a function because it has some consequences for the rest of the system that can be hard to realize at first. And it might get you into a situation where you want start using new functionality in the future that this customization will prevent you from using.
The standard functionality gives you a perfectly good relation between a sales order and a purchase order that you can use for reporting and to follow up both on your customers and your vendors.
That is why i am trying to urge you to really understand the standard functionality before you decide that it does not fill your needs and you will need a customization for it.
