Shelly Blu RC Button 4 hold to dim

I’ve just purchased a couple of these Bluetooth buttons to try out and wanted to try and use the Hold feature of the buttons to increase/decrease the brightness.
This would be similar to how some of my Control4 buttons and some old Lutron I used to have.

Given that the hold button only appears to lacerate a single event is there anyway anyone has made it perform incremental brightening or dimming?
