How to search through an Array of Containers

Hello 

Looking to search through an array of containers, meaning going through each index and then searching inside the container for the specified value

I'm aware of TestStands "Contains" function but that does not seem to look inside containers that are inside an array

So for example using the image above, i want to look in the "TESTING" array, then go through each container looking for the string value of "FindMe"

is this possible and how can this be achieved?
