Projectmix i/o and Keystation 88es volume control.

This may be a complete noob question but since I am a noob I will try here. I am currently getting comfortable with a newly acquired PMI/O. After 3 months I have a decent grip on things but am still baffled by one issue. It may not make sense but when using my Keystation 88 controller the volume pedal control passes through Logic and controls the fader on whatever track is active on the Project Mix. I know it's all midi data but I for the life of me can't figure out if there is a way to terminate the signal pre fader on the control surface. The reason for this is simply to reduce wear and tear on the faders while auditioning and practicing. Any input is appreciated.

Thanks in advance ....
