url settings

How to edit the url settings in ZPC?

Goal: replacement of "-" against "_"

Instead of:
http://example.com/link-to-album-or/news-title/album-title/a-b-c

i would like to have:
http://example.com/link_to_album_or/news_title/album_title/a_b_c

With TYPO3 I would modify the realurl_conf-ig file: 'spaceCharacter' => '_'
What is the realurl_conf in ZPC?

Thanks.
