Incremental archive from DynamoDB, Glue Bookmarking?

My customer is currently archiving DynamoDB data to their data lake with a Glue job and the DynamoDB connector. They've asked if instead of a full load each day they can do an incremental.

I see Glue supports bookmarking which looks like what I need but it only supports S3 (and some JDBC) sources for this.

Is there a way to achieve this?
