for a given eVar you can view reports with lots of metrics in SiteCatalyst.
you can filter on the different names the metric got in SiteCatalyst, but not on the values.
If I want to answer questions like " give me all pages where the name begins with valueX AND where the pageviews are >50" I have to create a segment for this.
Or export it to Excel and do the sorting and filtering over there.
It would save me time if I could do this in SiteCatalyst
