Would help a lot if we get a free retainer per expansion(depending on how much stuff gets pushed around) - another thing I'd like to suggest is...

Have a retainer just be the glamour "book" as such. They would be an artist and would draw all the gear you give them - but would destroy it in the process as such. You could then request a recreation of said item to use for glamour. That way it would be on the retainer system and only pulled when needed - not always loaded.
