Fibaro dimmers grouped to impulse switch

I’m controlling multiple Fibaro dimmers with one impulse switch from Fibaro Home Center 2. When I hold in the switch the main dimmer adjusts up and down, and the rest is following the main dimmer. How can I solve this if I want to use Homey instead?

Maybe you can try this app:

Thanks for the answer. I tried this, but I can only get it to work when I use the app, not the impulse switch.

You can make a flow for this I guess.
when dimlevel fibaro1 has changed → then set dimlevel fibaro 2 and 3 to dimlevel fibaro1
