I have asked one of the programmers about this some time ago and from memory they said it's because all the data is connected to that one account reference. I am sure that if it was simple to do Sage would introduced this years ago as it's been

This is because Sage uses the ID as a key, so, all records use this field. They should be using a hidden ID or something generic then allow a user to change this field... Third party tools exist that can do this and are annoyingly expensive. There is no reason why Sage couldn't release an update and a migration script that moved to a more modern format - or, simply a mass update tool like the third party ones that changes the reference everywhere.
