Hi Frank,
Thanks for checking out Event Aggregator!
It does include the option to overwrite events with the latest version of the source the next time the import runs.
I would also recommend taking a look at the following articles, which have some good details on the features that are available with Event Aggregator:
Managing Your Scheduled Imports in Event Aggregator
Event Aggregator Import Settings
How Do Event Aggregator’s Import Limits Work?
Importing Events from a Feed or URL
We do offer full refunds within 30 days of purchase, so if you’d like to take Event Aggregator for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
