Ability to build cohort segments

A classic direct marketing analysis is cohorting.  That is the timing of response, and grouping people (cookies in this case).  Once example would be visitors that visit 10 times in a month.  Or people that have visited 10 consecutive days.  Time is the dimension.  I know you can to this segmentation in Insight.  But would like to have the capability in Discover.  I have already provided Tim the mock up of what it would look like (and thought I had already posted it here).
