Create a compact homepage

Hi all, is it possible to create an inline list with independent screen configuration per item within ANOTHER inline list with independent screen configuration?

I think the answer is no because it’s saying I need to add a RowID column when I’ve already got one but just wanted to make sure I’m not doing anything wrong. Thanks again @Krivo for great video and allowing others to look under the hood.

EDIT: Ahhh sorry all. Just realized this is sorta a double post as I had typed similar comments in the other feature requests thread. Apologies as I’m still getting a hang for the forum layout.
