Import bookmarks from another browser

[Cybernettr at aol.com]

I noticed in OmniWeb that when you import bookmarks from another browser, 
they go under the imported bookmarks section, but this section cannot be edited.  
 You can't delete bookmarks, rearrange them, change their name, etc..  If you 
want to edit the bookmarks, you must go into the browser in which you created 
the bookmarks and make your changes there, then the changes are reflected the 
next time you launch OmniWeb.   Is the only way to make edits to these 
bookmarks to visit the sites in your imported bookmarks one by one in OmniWeb and 
then add them to OmniWeb's own BookMark collection?
