VW Tiguan 2021 2.0 TDI - dual SCR system

Good morning, I have a VW Tiguan 2021 2.0 TDI 122CV, our engine is equipped with the dual SCR system, therefore two DPFs.
The engine unit 18 works perfectly and displays the data of the first DPF, in fact you can see the values ​​of the high pressure EGR, while, by setting the engine unit 20, you see the data referring to the second DPF and low pressure EGR.
Would it be possible to have a screen with both engine codes, or rather the sensor queries, so as to see both SCRs at the same time?

Thank you

mmm ok dual SCR and dual EGR, but dual DPF I think you're wrong. I didn't see a system with 2 DPF.
