Mouse resolution for track envelope? (moving points with mouse) Ratio 1:1 possible?

[Reflected]

he guys

Do you know how can I change the mouse resolution for moving points inside track envelopes (without resizing the envelope track), so when I move a point with the mouse it will be 1:1 ratio - when i move the mouse there the point will move.

currently it's like 1:2 ratio.
moving the mouse 2mm up moves the point only 1mm up :/

in other words I want the moving ratio for the mouse and the envelope point to be 1:1 Regardless the size of the envelope track.

help please

thanks
