SYNAPSE 3: How copy key or light assignements from one keyboard to another?

Hi, I'm sorry if I not a normal user and I've more than one mouse and one keboard. I like Razer products but moving from one in use to a new device is HARD because Synapse-s fault or design defects. I've just chgd my Razer keyboard from an HUNSTMAN ELITE to an HUNTSMAN v2 and, with my disappointment, I-ve NOT FOUND any way with Synapse 3 to copy the old basic settings (text function/macro/assigements and lights) to the new keyboard. I use a lot the great functionality exposed by Synapse 3 ... but not all working good ;( A keyboard is a KEYBOARD. Any keboard have a LOT of identical keys or I'm bad? Why Synapse not understand that is a brand-new keyboard and tell me if I want copy the setting from the one of known keyboards. PS: I've 20 years of experience in developing SW for Windows and I tried to lookup inside the XML files, created when exporting the profiles, and I can modifiy with hands the file but seems very tied, too tied (enormously tied) to the device (model, name S / N !!!) and I suppose that your SW engineers have a utility to copy the setting.
