create a snap option for automation point values

I do a ton of volume automation, and it would be very nice if I could tell Cubase to snap to various increments - such as a quarter dB or a half dB. As it is now I have to type in a lot of values because just using the mouse I often can’t get two points in a row to land on the same value - and this isn’t OCD on my part; I have been told that fades consume more computer resources - so in order to avoid unintentional fades I often have to type in a value.
