Distinct Dimension count with metric => x
I've noted the function 'Approximate Count Distinct' which could be used for a count of the distinct values for a dimension however I'd like to extend this further and only count the distinct count where the value has had => specified metric value.
eg.
Distinct Headline count that have had 10 or more Page Views.
I'm able to achieve this if the table breakdown (rows) is headline but not without.
