Can the Faderport 16 use all 16 faders for track volume or only the first 8?

I have read that control surfaces using Mackie protocol can only use 8 faders for volume.

To access the faders on the second bank or more in the DAW you always need to use a shift key and use the same 1 to 8 faders on the hardware. Therefore the 9 to 16 faders are redundant with respect to track volume.

They can be assigned for send Etc but you caot in effect use all 16 faders to control track volumes 1 to 16 at the same time. Can anyone confirm this as I am wanting to purchase the 16 faders version but if they are not fully working on 16 chaels at once it seems pointless to pay the extra.

I am initially wanting to use with Cubase 9.5
