Bookings Report Automation?

Here it is, August of 2024. We have multiple ai engines in existence. We have reusable space rockets. We have advanced robotics. We have VR headsets. What do we not have? An update to Microsoft Bookings reporting capabilities.

I'm in a government account environment, so Power Automate isn't an option. MS Graph isn't an option. We're still operating off of a 2018 solution, an Excel connection to Online Exchange for reporting. We're unable to access custom field data without manually running the .tsv report out of our 18 Bookings pages. Even doing so, the custom field entries are lumped into a single column. I've opened a support ticket to Microsoft inquiring if there is a better way to access custom field data. Microsoft's answer was "no." 

Has anyone else out there figured out a workaround to automate access to custom field data in government account environments?
