Ability to customize hub URL hash

searchie .io/hub/1234567890 -> searchie .io/hub/customhash We now have pretty URLs for our pages, but we still have spam-looking hub URL hashes (searchie .io/hub/HASH). This request is for the ability to customize this hash to something more user-friendly and legible. The current recommendation is to purchase a custom domain, but not everyone wishes to do so for each of their hubs. This would allow us to retain the searchie .io domain and customize just the hash, similar to how we can customize our Facebook group names (facebook .com/groups/groupname) or Wordpress site subdomains (sitename.wordpress .com).
