In Segmentations, custome Metrics, etc I can use UNIQUES() in a formula to get a count of unique users for a given event. For example, use cases like the below for a conversion rate between two events:
%:UNIQUES(B)/UNIQUES(A)
However, I can’t do similar to obtain a count of sessions (unique session IDs) for a given event, such as:
%:SESSIONS(B)/SESSIONS(A)
This would be very useful, particularly for marketing channel use cases!
