Can I define loadable load in datacontext instead of query?

Is there a way to determine the desired load for the entire data context, so I can specify something like this: "when using this data context when loading, the Client always loads the corresponding City"?

So, something very similar to Options and LoadWith in Linq on Sql.

No Entity infrastructure offers the equivalent DataLoadOptionsavailable in Linq-to-Sql. There is no way to define something like LoadWithor AssociateWithglobally.

DataContext:

public MyDataContext() : 
  base(global::System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString, mappingSource)
{
    DataLoadOptions options = new DataLoadOptions();
    options.LoadWith<Customer>(o => o.City);
    this.LoadOptions = options;
    OnCreated();
}
