Can WMM be made to create clips automatically when a video file is added?

I have video files I created when capturing video from vhs. They are stored on my hard drive. I select one of these files to be edited with WMM. When I add one of these files to WMM the whole file seems to be 1 clip. In the editor the clips look all the same. Is there a way WMM can be set to make smaller clips from the added file without manually cutting them? This would make editing these large files much easier.
