You mean with all the framesets and related pages ? No, 
this option is not yet implemented (it is a bit complex to 
implement, but might be done in the future)

If you just need to capture a page with all dependencies 
such as images, styles and scripts, just use scan rules:
-* +*.gif +*.jpg +*.png +*.css +*.js
