I'm not sure what kind of store configurations you might have, or how similar they are, but there isn't a
glu-specific way for you to configure lots and lots of
comboboxes. Typically there are common configurations, but in my cases I've always had some kind of change between them which prevented me from making any kind of factory that would create everything for me. Sorry there's no magic there to help you out... but its not that much work to have the basic {type: 'combo', name: 'combo1'}. Good luck, and if you find a better way, definitely let me know :)
