Push button with dimming function

Good afternoon,

I connected a Shelly Plus 1 to a power supply dimmer with Push Button input. I configured the Shelly that when I press ON it wil activate for 0,2 seconds so the light is swithing to the last know dimming value. Now to dim the light I need to give a push command for a few seconds, but this is not possible because I configured the Auto on function for 0,2 seconds.

Is there another way to do this ?

So when I push the 'on' button in the app short the light must go ON or OFF. When I keep pushing the on button the output must stay close untill I stop pushing.

Thank you for your support !
