Multiple deepclick buttons NOT acting as different analog sliders

Multiple deepclick buttons NOT acting as different analog sliders

i have a Z2 and I'm trying to configure 2 deepclick buttons as analog throttle and brake for racing sim games, and since Xinput is still not supported i'm using X360CE. However, even though the mouse has 4 different buttons with this feature, they all output to a single analog range, which defeats the whole purpose of having that number.

is there any workaround for this?
