Show On AND Off buttons (instead of toggle button)

[Netsurfer24]

Hi,

I am totally new to Domoticz and facing a problem, which I cannot solve.
I use Domoticz on a Raspi Pi 3 with the RFXCom Transceiver, mainly to switch my several Intertechno plugs and switches.
Some of them are Dimmers, but inlike the newer ones, where you can set the level simply by a percentage value, you have to start/stop the dimming by pressing the On button.
Turning these switches on and off is done by just sending the Off signal (this will toggle the state of the switch).

So what I am looking for, is to have both buttons (On and Off) instead of the standard (one button toggle) switch on the dashboard.

BTW: In the app "Domoticz" there is a simple config option for just this.

Could I achieve the same for the Domoticz dashboard? ANd if so - how?

Many thanks in advance!
