Cars DSG gearbox with multiple final gear ratios possible in AC?

[MYS2220]

Hello.

I'm working on a car (MK6 Golf R DSG) which apparently uses different final gear ratios for gears 1-4 and 5-6. I've searched high and low but haven't come across any info on whether thats possible in AC? I cant find other Kunos cars which have that.
I know you can use final.rto to change your main final gear in the pits but can it dynamically change it by itself?

Hope that makes sense and any info hugely appreciated.

Not a thing, just incorporate it into the individual gear ratios. So if 5th is 1.0, turn it down to 0.75 or whatever it'd be if it used the 1-4 final.
