Is it possible to save Server reply inside Sent Form?

I have a form that once saved will have an ID generated for it on the server side. When the form is sent, I want the ID that is replied back from the server to be part of the "Sent Form".

What I am doing currently is reply the ID back and the user will scribble it on a paper.

Is there some workaround to accomplish this?

Why does the user need this ID right away?

I am struggling to see the need for this.

My guess is that Alex_S wants to see the list of sent forms after a device reset.

Sorry Stuart for the late reply. Our user are trying generate voucher codes from our server by submitting data. They need the codes after submission. We however want to let them submit multiple instances and put the generated code inside the "Sent Forms". Am I clear?
