Shelly Plus RGBW PM Dimming via Momentary switch

[Jphannon1]

Is it possible to get the lights to dim via the switch the shelly is connected to (momentary switch). In the official shelly software the default behavour, means the lights dim up if the momentary switch is held down and then dim down, if held again, but when using this firmware it just turns them off.

Is this possible? Or could it even be added?
