Knobs: Absolut to Relative Conversion

I have some knobs on my controller that I can't change from absolute to relative on the hardware site.

So - using CSS - I would like to map them from absolute to "relative", so I can use the respective Ableton controls in a "relative fashion". (+1/-1) if I turn the knobs a little.

Is there a way of doing it?

I tried:

A) Controller Template - Mapping: Absolute 0-127 -> Script Mapping Relative L0, R127, 128 streps --> Not working
B) Controller Template - Mapping: Relative L0, R127, 128 streps-> Script Mapping Default --> Not working
C) Controller Template - Mapping: Relative L0, R127, 128 streps -> Script Mapping Relative L0, R127, 128 streps --> Not working

Any support is highly appreciated!
