NS Cloner Pro Intergration with Restrict Content Pro

I need your assistance in the creation of a hook/action for subsite templates originating from NS Cloner Pro to/between Restrict Content Pro Site Creation addon. Without the hook, the Site Creation addon defaults to standard wordpress site creation. The goal is to initialize NS Cloner functionality on the Restrict Content Pro registration page. Here are some docs from NS Cloner Pro:

My thanks in advance. John
