+
+### Changed
+- Changed Approved Jobs import behavior to only apply `autotask_company_id` and `autotask_company_name` when the new import option is checked
+- Changed Customers CSV import behavior to only apply Autotask mapping fields when the new import option is checked
+- Changed import success/audit output for both jobs and customers imports to include whether Autotask IDs were imported
