Zoom in / out with mouse wheel

In my app i can zoom in and out by scrolling with the mouse wheel.
Now I want configure "fn+scroll up" and "fn+scroll down" to move as fast as possible to the max in / max out zoom position and used the following settings - but this doesn't work.


Any suggestions ?

Macbook Pro, Logitech MX Master connected with bluetooth, Logi options installed

Same issue here. Would love to use the mouse wheel for a bigger / smaller brush in Photoshop. Did you find a solution?
