How to export Azure Compliance Data for NIST 800-53 r4 in a PDF format

I am doing security audit and have to provide recommendations to my customer based on the Audit outcome. I have created a NIST 800-53 R4 Policy Initiative and assigned it to few subscriptions. So i would like to export this compliance report now in the form of a PDF or a CSV. How is that possible? I don't see any option to export the compliance report. You get this option in Azure Security Center for CIS, PCI DSS, SOC TSP and ISO 27001.  I want something like that in Azure Policy. Can anyone help me with this or provide some pointers. Thanks
