Benchmarking against Customer Cohorts

The ability to benchmark a customer against its cohorts would be a powerful tool. It would allow CTAs and Scorecards to really hone in on the stragglers within a cohort as well as allow the CTA and Scorecard configuration to grow with the business as opposed to pegging it to fixed thresholds. This would be so cool!
In the April Release, we can create rules that aggregate data across accounts within a segment or cohort to establish benchmarks.  So can we declare victory for Marie's idea?
