Drupal Console: Create new multi-site with URL

drupal multisite:new testing1 testing.site

NB: The URL above is not meant to be a link.
--learning
The output will become very verbose and provide instruction on how to automate this. In this instance, this is quite useless. This does nothing for us here.
testing1
This is the directory to be created.
testing1.site
In theory, this should be the URL included in the sites.php file, however it is never used.

Alternate, again not working attempt:

drupal multisite:new --learning --uri="http://testing.site" testing1 testing.site

NB: The URL above is not meant to be a link.
