Combine light switch and dimmer in the same homekit item

Hi friends,
I read on the Homekit Add-on documentation page that it is possible to set up a Homekit item to show 2 switches for the same item on the iOS Home app
The documentation page did say that there is currently a limitation that doesn’t allow to combine two lights.

Will it be possible to combine 1 light switch and 1 dimmer? or will these be considered 2 lights?
Myabe I can set the light switch homekit metadata as a Switchable device instead of Lighting, and the the second dimmable device’s homekit metadata to Lighting and Lighting.Brightness?
