A: Building customized reports isn’t part of our service offering. The Power BI reports are provided as-is and as a service to enable customers to adopt these into their own environment. They are built in Power BI and not a proprietary system in order to facilitate easy adoption/adjustment by Microsoft centric organizations that utilize Power BI.
