Whenever I drill down a report by segment, the idea is to see how relevant that segment is for that particular data and then start doing analysis.
What happens is that when you are looking at all visits/users in aggregate, when you run the segment it replaces the data by the segment data, without showing any reference to the aggregate.
For example, what you see is this:
Campaign x - Drilled down by segment "y"
What I would like to see is this:
Campaign x - all users/visits
From segment x - % of total
From segment y - % of total
This would save me a lot of time going back and forth different segments and have to input data into excel manually or having to set up dashboards for something that I want to see as a one shot information.
Help me promote this idea and save us precious time. =)
