Hi adamcodes716,

Thanks for using Fabric Community.
You will need to do this KQL Queryset with 2 lines of code: mv-expand operator and bag_unpack() in KQL language. You can put these inside a function and call this function from Update Policies to transform this data on the fly.

Docs to refer -

mv-expand operator - Azure Data Explorer & Real-Time Analytics | Microsoft Learn
bag_unpack plugin - Azure Data Explorer & Real-Time Analytics | Microsoft Learn

Hope this is helpful. Please let me know incase of further queries.
