Hi there,
Thank you for reaching out to us!
Scheduled imports will update your events based on your configs at Events -> Settings -> Imports -> Event Update Authority.
You can choose between three options:
1- Overwrite your event with any changes from the original source.
2- Do not re-import events. Changes made locally will be preserved.
3- Import events but preserve local changes to event fields.
Based on your request, I believe the third option is what you are looking for. You will find more information about these settings in the following article:
Event Aggregator Import Settings
I hope this helps! If you have any other questions at all please feel free to let me know and I’d be happy to help as best I can!
Cheers,
Patricia
