Retention Policy For Sent Reports

We believe there is a current security and compliance issue with the unlimited retention of reports in the "Sent" reports section. There is no way to automate their deletion after a given time, and no way for BrightGauge support to do it in our behalf. The only method we have found is to manually sort the "Sent" reports in ascending order by age, select all (applies ONLY to the current page), delete, repeat... This is unmanageable, and even if we use a macro recorder to complete the task, we still have to manually set it to run and then watch it to make sure it doesn't delete files inside our chosen retention time.
