Creating average of averages

Hi folks, I'm trying to build an average of a group of indicators that share common elements but can't seem to group them. As you can see, I have an Indicator column and what I want is to create a "family" of those indicators ie. Create an average of the Average of Score I have already. Is this possible to do in Metabase?

Hi @osmont
I don't understand. Why can't you create another summarize section and do average of average?
