Apple News Format 2 column container with different widths

https://developer.apple.com/documentation/apple_news/collection_display#see-also


Hi, I have a container using the following with a nested image and text component that both take 50% of the width of the container which is great for mobile, but for tablet, I'd like to be able to specify the maxwidth of only the image so that it takes 30% or a column span of 3 for larger displays.


Does anyone know how to achieve that type of layout?


"contentDisplay": {
  "type": "collection",
  "gutter": "15",
  "rowSpacing": "30",
  "distribution": "wide",
  "variableSizing": true
  }


thanks!
