I think it would be very helpful to have a Key Segments report. It would
be just like the Key Metrics report, but instead of selecting multiple
metrics and having them trended against each other, you would instead
select multiple segments and see them trended against each other. There
isn't currently a way to pull multiple segments into a single report and
compare them. Trended reports work great for comparing variable values,
but many customer segments aren't defined exclusively by one variable...
