We have a case where we sell our device (with unique serial number) bundled with either a 1 year or 5 year subscription.
In order to do this we use the production module to create the bundled product. The drawback with this is that the original SN of the device is no longer accessible for picking or packing slips and therefore no way of knowing what device is being sent to a customer.
Would like the option to keep the original SN and not have to use the newly created FG number.
Or as an interim measure an easy way to tie the two together, e.g.
FG-001 = Device SN 1234
FG-002 = Device SN 1235
