Allow for more than 5 items on show when breaking down multiple values in an evar report

[#1]

Only showing 5 creates significant problems when dashboarding this data. Since the user is presented with 2 options. Stick with only seeing 5 items or select a single evar to see all breakdowns. 

In my use case I want to breakdown across multiple values and increase the limit to at least 10 so I can dashboard that data.

I totally agree! This would be tremendously useful for easily creating more reports.
