Which Analytics 360 feature allows you to create a new data set with a broad view of your business across products, brands or regions by combining data from multiple source properties?

Roll-up properties are a Google Analytics 360 feature designed to aggregate data from multiple source properties into a single new property. This provides a consolidated view of business performance across different products, brands, or regions, which is crucial for large organizations needing a holistic perspective. Data streams are individual data sources within a Google Analytics 4 property (e.g., website, iOS app, Android app), not a way to combine multiple properties. Organizations are the top-level entity in Google Analytics 360 that groups accounts, but they don't combine data into a new property. Subproperties are a GA4 360 feature that allows filtering data from a single source property, not combining data from multiple properties.
