Triple switch cover

Hi. I’ve already got a few Hue bulbs and would like to add my kitchen. The problem is we have 3 zones to light all controlled by 1 triple switch, and we want to keep them as 3. I can find double switch covers for the Hue dimmers but not a triple. I could screw a single into the wall next to the double cover but it wouldn’t look as neat as a proper triple. Does anyone have any ideas? I can see some that will fit old fashioned looking USA switches, but I’m in UK and I need something that will screw on with 2 screws, 1 on each side.
