Is this even possible?
There is nothing more fustrating than only the two available options, having your sim make one ... at ... a ... time to get a variety of each product in your store or keep making many of the same one until you have to cancel the queue which makes for no variety and constant babysitting them IMO.
I think it would make more sense to have make 1 or 5 or 10 as your store needs it.
