Audi Drive Select not coding

[MarkWizard]

Hi All

Not sure if anyone else has tried coding this:

I can tick the box for "Drive Select" fitted in byte 7 but then byte 8 only had the one box available which is for magnetic ride (which I don't have with it being the Allroad).

Any ideas please? Can I just change the binary coding manually?

Thanks

Mark.
