Is there a way in 3D Flash Animator 3.0 to add some sort of preload-function??

I know how to do it in Macromedia Flash 5, but I find 3D Flash Animator much easier to use. So I tried to import a swf file made in 3D FA into MM Flash, but I run into some problems with that. So I'd like to realise the preload-function within 3D FA.

Please help me, the information provided in the helpfiles from 3D FA is very little.

thnx
