Mackie MCU - matching physical and virtual fader positions

Hi all, a quick question if I may: is there any way in Cubase 8.5x to calibrate the virtual faders in the mix console so that their positions match the physical faders on the Mackie MCU Pro (and its extenders)?

For example, if I set a physical fader to 0dB, it shows up at around -0,92dB in the mix console:

Now, this might sound trivial, but when you’re looking at the mix console full-screen on a 40" 4k monitor, you can drive a truck through the discrepancy. Most irritating.
