Ah now I understand. Thanks for clarifying!
You aren't seeing the option in your settings because there isn't a dynamic list element in the teal section.
One option is to add in a another dynamic list element from the add panel, then nest your elements accordingly. (i.e. Section > dynamic list > rich text block)
The other option it expand your current dynamic list to incorporate the teal section.
One of these should solve your issue!
Hope this helps
EDIT: Here is a GIF showing the first option. the second might get messy.
