Is it possible that I can add `Table<T>` dynamiclly to an exisitng DataContext Insance in LinqToSQL?

Here is my case:
 I have several classsed which are using [Test] attribute to declared as Table, I want to allow user to create the corresponding SQL Server tables during run-time. I understand that If I inherit the DataContext class, I can add member
 Table customers;
in the class and it will automaticly create such a table at the backend database. 
However, the problem is that whether I can add Table during run-time to a DataContext class which help me to create the correspondgin SQL Server Table corresponding to T.
