Toad Data modeler scope request

Hi Folks,

  I work with the toad data modeler and we have a large database with many users.  I would like a way to limit the processes Update model from the database and Generate change script  to just a schema and set of tables.  Currently it gets all the users and roles and directories not related the schema or tables.  This costs considerable time as it may take an hour just to process the users.


Thank you
