Hmm,
You could archive the order to keep a copy of it, the only issue there is that you cannot use an archived order as a source for creating a new order,
I think your options will be to either:
Have the orders remain in the system but get a development done to hide them from the users therefore they are available to copy
Have a development done to modify the way the system posts to allow the zero PO to be posted through and then it will sit as a posted order available for copying
Not sure what the best route will be as both solutions will need development, i would say have your NAV partner look into both options and make a call based on how complex the solutions will be
