custom layout for grouping

There is a dynamic layout on sample site Showcase that rearrange the position of the visuals into columns. https://microsoft.github.io/PowerBI-JavaScript/demo/v2-demo/index.html# We are using this feature but the thing is that we are also using grouping in Power BI Desktop, as described here https://docs.microsoft.com/en-us/power-bi/desktop-grouping-visuals Some of our visuals are grouped as whole. When group of visuals is embedded while also using custom layout. The group got separated and our design based on the grouping will not be displayed. We would like keep the visuals grouped(as it is displayed in Power BI Desktop) and not separated when it is embedded with custom layout. It would save lots of work if we are able to keep the visual grouped. Can we keep the grouping when embedding with custom layout, and rearrange the position of groups along with single visuals that aren't grouped together?
