Rotations on 3D Viewport with Ctrl + Alt + Wheel and Ctrl + Shift + Wheel

Hi everyone

In blender 2.79b we had the possibility to rotate in the 3D view on the x and y axes with the increment Rotation Angle of 15 ° of the User Preferences.
The shortcuts were Ctrl + Alt + Wheel and Ctrl + Shift + Wheel
On 2.8 I can not find this possibility. I find it a pity
Is there a way to do this ? Thank you
