@ddabcd277,

You know more about me that I know myself... LOL! Seriously, I do not have this knowledge. There are reasons why the 1xxx models could be updated using the logo string, but I doubt this applies to the 6x0 models. If you want to try, you can make the string 5 or 6 characters and try. For example, the SKU is in the form of D0681-00 and only 681 is written. The 0 zeros seems to be removed or optional. Nothing prevents you from trying 68110 (D0681-10), 68160 (D0681-60), etc...
