Create WhatsApp Templates With User Fields

Now when we create a WhatsApp template, we set "unknown" variables from 1 to 10, and then, in the flow, we need to relate for each number the user field, There are 2 major problems this way: 1. restriction to 10 variables 2. more work to set whatsapp template, cause must use flow, and not just whatsapp template. The best alternative solution will be to change the way it works and to do it like Manychat, In Manychat you can put the variables in the template message directly and you don't need to do it from the flow..
