Change Table Name of an Entity on runtime?

There is this table that is being generated on a monthly basis. Basically the table structure of all monthly tables is the same.

Since it would be a lot of work to map the same entity just with a different table name,

Is it possible to change the table name of an entity as follows on runtime since they have the same table structure after all?

   @Entity
   @Table(name="FOO_JAN2010") // any other ways to generate this dynamically?
   public class FooJan2010Table {  // if we can dynamically set the table name this can be simply named FooTable
       ...
   }

If not, what approach can you suggest?
