Url aliases for participatory spaces

Currently it's possible to choose the url slug for the participatory spaces. It would be great to be able to enter aliases (like it's possible on wordpress or drupal) so that we are able to communicate on simpler urls and get rid of the /processes/url-slug or assemblies/url-slug. Furthermore /processes and /assemblies are english terms we cannot translate in i18n. Ex : meta.decidim.org/roadmap/
