GreenLight: Add content area block (Site width)

I am only using the Greenlight Element blocks. I am trying to create some sections but came across this issue with inner container.

I added the content block it has one inner div container site width 1200.

But when I want to added one more inner container I don\’t see that element exist in the panel.

It seems like this Content Area block appears only when we add the Content Element block and we can\’t add one more Content area block if we have to add at later stage. Very strange. Why can\’t we add new Content Area Block if I want to have one more container in the same section.

There is main, aside, div, section etc but not the actual useful content width div (container)

Also a recommendation we can remove these extra div presets and possibly keep only Main Section (Full width section), Container(site width element), Block (100% width) and Div (Plain div)

Thank you
