Flash 8: Buttons and movieclips

Im a newbie so bare with me.

I got one movieclip with several buttons and another movieclip where i use:
this.loadMovie(“news1.swf”);

What Id like to do is, if its possible, to do, on the main timeline, assign, to the buttons what news.swf to load into the other movieclip where i load it.

So i can assign one button to load news1.swf and another load news2.swf. I think you guys get the idea here.

Is it possible and if how?
