Bulk download routing run report

Summary:

We need field managers to assess the routing run reports for all routing plan executions for a particular day to identify the reasons for which there are max no. of routing failures for each of the zones for which routing plans have run. This will help them identify which zones or which runs have low performance to be able to deep-dive into root causes.
For this they are currently manually downloading the reports for each run separately and then consolidating the results. They require a dump of all detailed data in the routing run report.
Please advise if there is any way to bulk download these details using any existing API or other mechanism.
