The best way to do this without adding extra components is to make use of a copy (or multiple copies) of the original volume knob/fader. Then, either on a design schematic page or UCI page/layer:

  1. Convert the Presentation property to "Button".
  2. Covert the Push Action property to "String".
  3. Add the Button String property. For example, ++1, --1, +=3, -=3 will respectively increase the volume by 1dB, decrease the volume by 1dB, increase by 3 dB, or decrease by 3dB.
