Hello John Campion,
I am afraid that at the moment this option can be enabled only by using Fluent mapping. You will have to use Fluent mapping for all classes containing DateTime properties which should be updated automatically and call the IsCalculatedOn method for each of them:
classConfiguration.HasProperty(c => c.Date).IsCalculatedOn(Telerik.OpenAccess.Metadata.DateTimeAutosetMode.InsertAndUpdate);
Please excuse us for the inconvenience caused. We will try to include this option in the designer for one of the future versions of the product.
