How do i group all rachio sprinkler zones into a single "homekit accessory"?

Right now, each rachio sprinkler zone shows up as a seperate accessory in homekit when i use the homekit bridge. I would like to group them all into a single accessory as shown in the screenshot below. How do i do this? i saw this youtuber had it done for their smart sprinkler

When I do that with some lights it doesn’t look like the screenshot I posted. Did apple home change how this used to work or something?

Also, I told HomeKit bridge to treat these devices as a “sprinkler type” and I don’t even see the grouping option on these sprinkler zones ( unlike lights mentioned above and in your screenshot )
