I don't know, what you mean by "multi trimming".
If called from PowerDirector, the currently selected audio clip is made available for editing. You cannot call AudioDirector, if you have more than one clip selected in PowerDirector.
But if you start AudioDirector 'standalone', you can add more audio clips at the same time.
Trimming is done in the "Mix" tab. Drag the clip (audio/video) to the timeline.
