Is it possible to add my own pre-installed script on my site

Is it possible to add new choices in the "pre-installed scripts" section of cpanel? If so, where can I find documentation for this?

I'm interested in seeing if it's possible to get the CivicSpace content management system (CMS) setup as an installable option within cpanel just on sites that want it. (CivicSpace is a superset of the Drupal CMS)

Fantastico could be a solution, but according to their forums, they already have too many CMS's in their menu.
