generate omn classes only for a subset of tables

Is there a way to configure Torque generator so that it generates om
classes only for a subset of the tables in a db ?
I will use the ability of torque tu support multiple database to import
some data from a secondary db, but I need to use only a small subset of
tables (5 out of 40+)  of the whole db.
I will get metadata from a MySQL db and the filter should be set either
for the jdbc task or for the om task.
