Formatting in Power BI Report Builder

Hello,

I am trying to create (well, mimic) a report from another system. I have the data sample to work with but I just can't seem to get it to display the way I want.

For each row of info, it should display a list like this:

How do I get my report to reflect the first format for each row of my data? I have the first piece in a column Group and the bottom table in a Row Group, but just struggling to get hte format I want. I feel like I'm close so any directions, suggestions, hints would be appreciated!
