The ability to combine/merge items into one.

One typical problem situation is when a department in a company first manually enters equipment(computer, mice, monitors, usb devices,printers, network devices, simcards, phones, etc) from orders and then there is a record completed by an agent whether GLPI or Fusioninventory.

Everything is ok until the wrong serial number is entered in the manually entered record (or the numbers are entered from the typist's head :/).In such a case we have a problem because 2 separate items begin to function in GLPI , one entered manually with important accounting and administrative data and the history of their changes and the other entered by the agent with technical IT data.

There is no possibility in such a case to merge them into one correct record with preservation of the history of changes.
With preservation of changes also in the fields added using the fields plugin.
