Shelly dimmer 2 long press momentary switch

    Hallo, I have shelly dimmer 2 with momentary switch.

    this dimmer is super, much better than tuya with lot of functions.

    I did the action:
    Output switched OFF url: http://localhost/light/0?brightness=100
    so that I always have 100 brightness when I turn it on.

    But here is problem.

    Momentary switch works so, that when I press long momentary switch, Brightness go UP. But I already have 100% by function. So it make no effect. Then I have to one more time press and hold momentary switch to go brightness DOWN.

    So my question is:

    Is it possible to replace momentary switch function, that First long press make brightness DOWN, and second long pres make brightness UP?

    Thank you.
