Having an ability to sum single or multiple source report row counts to a dashboard panel

What is the challenge?

We have metrics around improving the hygiene of our Aha data input using List Reports. Currently 12 different views across the data (and seems impossible to consolidate as a single big filter correctly) and would like to present the improvement weekly as a single row count across all reports.

What is the impact?

Currently I need to run each report individually and tally up to provide the metric

Describe your idea

Having a dashboard item that provides a count of one or a number of source report rows and sums to provide a single number total displayed.
