Push - Touch Strip relative control

[Liine]

I'd like to set the Touch Strip in Push to behave relative to where I first touch it, like the ribbon on a CS-80. As it is, I have to very carefully aim for the middle of the strip to find the zero point, then I can move up or down to pitchbend my synth. I'd like the zero point to be wherever I first put my finger down, then pitch up/down relative to that first contact point.
