How to enable HTML Email Templates, activated for various websites such as other plugins?

Hello,

Please help. How to enable HTML Email Templates, activated for various websites such as other plugins? For now, it appears the HTML Email Templates can only be activated for Network only. So all websites have to use a similar template and can not be modified. Only Network Admins only can change the template. By the other customers do not have the right to change the template, because they have no plugin that can be activated to their website.
