Hello Michal, this function is not included in the gtk slider functions and there is no quick solution for this.
I also do not see the need for this, can you explain the situation where you/your co-workers need this. Do you know the "auto enhance" button and the shadow/highlight sliders of xsane? If you scan negatives/slides you better should define medium types in which contrast, brightness and gamma are stored for each color separately. This also can be used for othe media like photos, but I do not know if a common medium definition is applicably, but you should try.
