Users can review bundle objects that will be installed and set preferences for those objects on the "Preview Bundle Install Page" in NetSuite. This page is presented during the bundle installation process and provides detailed information about the contents of the bundle, including scripts, custom fields, records, and other components. It also allows users to configure certain preferences and settings for the bundle before completing the installation. This step is crucial for understanding the impact of the bundle on the current NetSuite environment and ensuring that configurations align with organizational requirements and standards.References: NetSuite Help Center, SuiteBundler Guide.
