So there is <AlertRefID>74913425-d003-4b48-bcb0-96a049f31ca6</AlertRefID> at the top of exported xml. I fixed some parameters and want to import it as new alert. If I use the same AlertRefID, I got error. Also I got error if I leave this Ref blank. How can I generate a valid AlertRefId to import several alerts? I have ~50 alerts to import.
