DB_DataObject table prefix?

Hi, Is it possible to specify a table prefix for tables used by DB_DataObject? I've just had to add prefixes to all the table names used by my current project, and this of course means that DB_DataObject's auto-building creates new class files with different names, which means a lot of manual changes around the site. eg... My .ini had this in it: require_prefix = DataObjects/ class_prefix = DataObjects_ and I had a table called 'person' and a class called 'DataObjects_Person' in a Person.php file. After adding table prefixes I have a table called 'myproject_person' and a class called 'DataObjects_Myproject_person' in a Myproject_person.php file. I guess being able to put: table_prefix = Myproject_ in my .ini file would be ideal but I can't find anything like this in the documentation. Any thoughts? Phil
