Layout header-columns-footer adding tabs

[eraldop]

I have installed the latest version of jupyter-flex (0.6.5). I'm trying to build a layout similar to the example notebook "header-columns-footer" where the second column in the body of the page uses tabs.
I tried many different configurations but what I cannot find is a way to change Sections orientation multiple times on a specific page, like this:

# Page X    ->  selected page     tags: orientation = rows 
## Section 1  -> header 

# ...... missing -> change section orientation.    tags: orientation = columns

## Section 2 -> first column 

## Section 3 -> second column with tabs.    tags: tabs 

### Card 1 -> first tab
### Card 2 -> second tab

# ...... missing -> change section orientation.    tags: orientation = rows

## Section 4 -> footer  tags: tabs  (to have multiple information separated in different tabs) 

### Footer 1
### Footer 2

Any help is appreciated. Thank you so much for this handy package. It rocks ;)

I know its a super late response but this is not possible with the current expressions, it would require to be able to specify a section inside another section.

It's possible to implement this but not sure what the best way to make it clear in the UX, maybe a child-section tag or something like that.
