Is there a way to define a SQL trigger-like mechanism in EF4?

I need to create an audit log like feature where most of one table's fields are copied to another when they are modified. Normally, I would create 开发者_StackOverflowa SQL trigger to do this.

Is there an Entity Framework 4 equivalent, where upon modifying Entity X I could modify Entity Y?

There are some approaches out there on using ObjectContext.SaveChanges and the ObjectStateManager to perform such auditing requirements in EF
