Shelly 1 question

So if I have a momentary dumb switch on my wall and connect this to a shelly 1, I've established I can send mqtt signals through my HE to turn an H801 led strip on and off

What I would like to know, is there a way to be able to push and hold my dumb switch and have the h801 dim the led? In a similar fashion to how my momentary switches work with my fibaro dimmers. Push on off, hold to dim

Fingers crossed....
