Preload loadmovie into Main

Sorry, I am tired of looking for an answer for this and just want to know if it is at all possible.

I have my mainmovie, in which I’m loading external .swf’s using the “loadmovie” command. Now, everything works perfectly, loaders and all. The thing is, that since they are all so heavy, that once you move to another section (external .swf) it always takes a few minutes to load.

Is there a way to make these start loading while on the mainmovie? So that when clicked upon loading time is reduced?
