Summary: Currently, when users export schedules to CSV and re-upload them — even without modifying certain activities — any existing comments/descriptions on those events are removed. This causes data loss and extra manual work for teams using CSV uploads for bulk changes. Current Behavior: Comments/descriptions are included in the export (as of July 2025). However, when the CSV is re-uploaded, the import process overwrites all events in the selected time window. This means that comments/descriptions on unchanged events are deleted, even if the event itself wasn’t edited. Desired Behavior: When re-uploading a CSV, Assembled should preserve comments/descriptions for any events that have not been modified. Ideally, the CSV import process should support one of the following enhancements: Selective overwrite – Only update events that have changed (based on event ID or modified fields). Preserve comments toggle – A checkbox or setting to retain existing comments during import. Ensure comments are included in both export and import without loss.
