I was thinking about something and thought about a numbering system on formation designer so we can have our own loco like 8F 48151 or 45596 Bahamas it would be fantastic.
Yes especially for some US locomotives where I get a custom livery for say NS 1111 but the headboard will show a different number. So if I could spawn in the custom barcode unit and then make the headboard 1111 that would be amazing.
