New row in a repeat by group

I have an org chart on our internal web page that displays employees by manager. I would like to start a new row each time the “level” changes (you know so he boss is at the top) What is the best way to start a new “group row” based on their manager group level (the field I use for sorting)?

I’m using cards so i have a new card for each manager with the employees that report to them. I simply want to put those cards in a new row for each manager group level
