C# get Linq Table from generic

I have this repeating method in my classes (some lines have been removed to simplify the question):

public void CreateNew(DBContext db, SystemMessageReport newRec)
{
    db.SystemMessageReports.InsertOnSubmit(newRec);
    db.SubmitChanges();
}

Ideally, I'd like to be able to move this method to it's parent class as a generic method.

If SystemMessageReport is passed as T, is it possible to InsertOnSubmit to it's correspdonding Linq Table? For example:

public void CreateNew<T>(DBContext db, T newRec)
{
    db.T.InsertOnSubmit(newRec);
    db.SubmitChanges();
}
