Currently only the selected URLs can be pruned or be recrawled. If you would like to prune or recrawl the outlink URLs, you have to expand the tree nodes and select all of them.
A more complex scenario is you would like to prune or recrawl an URL and it's outlink URLs, but would like to exclude part of it's outlinks URLs.
It's would be useful if the users could prune or recrawl the URLs and it's outlink URLs in one session.
