DJM-S11 Disable FX Level/Depth for Serato

Just started using the DJM-S11 and I would really like to control the softwareFX of Serato individually and also not snap to the level of the Level/Depth-encoder. Having up to 7 FX at the same level seems like no use for noone. I know I can go into the midi control on the mixer and control them individually there, but as soon as you touch the Level/Depht-encoder all values snap to the position.

So the first step for me would be to disable the control of the SoftwareFX and use another midi-controller for controlling the level of the Serato SoftwareFX.

Is this possible?

Thanks!
