running a KPI report in DPA from CLI ?

I run a KPI report daily at 07:00 daily and mail a set of users the results.  This works well.

However, I'd much rather just add each day's output (a single line, comprised of about six fields such as backup success %, total jobs run in the last 24 hours, total TBs backed up, etc.), i.e.

9/29/2015,99.951,11,975,57.23

... to a .CSV so that I can track such things over time, like this

Date,Success_Rate%,Total_Jobs,Total_TBs_Backed_Up

9/27/2015,99.972,12515,56.25

9/28/2015,99.875,11672,55.93

9/29/2015,99.951,11975,57.23

Surely there must be another DPA user out there whose mgmt has requested a similar function?  I opened two different SRs with Support but got the perfunctory "you'll have to speak with your account manager about a Professional Services engagement" response. :-/
