USB multi-channel possible?

[Muberos]

I have an RME ADI-2 Pro and when it is operating in USB mode, it is possible to select 2-channel or multi channel. Is it possible in Vinylstudio Pro to select which USB channels to record from, or is it fixed at channels 1/2?

For info, I've solved my question of multi-channel USB on the RME interface.
Multi-channel USB is only available when PCM recording is selected, I normally use DSD. In addition, the maximum sample rate is 192kHz.
Once it is set up like this, the USB channels appear as inputs in the dropdown list in Vinylstudio.
