Hello,
You can do that if you add several grids in the layout configuration:

Here are examples:

Unfortunately, with that approach, inline editors won’t work in the second grid. The dev team will fix it in the future, but I cannot give you any ETA.

If you need something different, please, describe your question in more detail.
