Preloading movieclips with linkage names?

Hi guys,
I have a flash movie with a lot of linked movieclips in my library (mc’s with linkage names). I have a preloader in the beginning of the flash movie. However, the preloader doesn’t show until (I guess) all those linked movieclips are downloaded first. Then the preloader starts showing, starting at something like 40% . How can I include the linked movieclips in my preloading, such that the preloader shows straight away, from 0% ?

Thanks
