Count items in a flat list?

[CommunityMember129223]

Hello, 

I am trying to count how many items are in a list and display it in a module?

In the example below we have 3 items in the list. 

Does a function like this exist?

Create a system module (with #promotion flat as a dimension) with a line item called "count" and a formula of just "1".  Create a second module which is a "totals module" (without #promotion flat as a dimension).  In the totals module create a line item called count that directly references the system module (system module.count).  It should naturally grab the top level.

Thanks! That worked. I was overthinking it.
