Good afternoon

I want to customize the emails that the system sends for different user interactions.

In the list of views in the HikaShop admin panel, I found several template, including those currently used on my site, but I couldn't find how to frame one of those views to use it. For example, for user registration, it seems that user_notification.html.php is used, but I found others like alternative_green.html.php and others. So, if I want to stop using the default view and use the green alternative, how do I do it?

Thank you very much!
