Ignoring existing tables?

[Tad <ta...@gmail.com>]

Is there a way to make the modeler ignore existing DB tables that I
don't want it to touch, during reverse engineering and (especially)
migration? I have a unique business constraint that requires me to
create a schema within an existing database, even though the new
tables have no relationships with the existing ones. If I make a
schema change within the modeler, it wants to drop all of the tables
Cayenne doesn't know about, and I have to manually scan and ignore
these entries.
