Same interface template on more than one interface

[ciscoworlds]

Hello;

my lab topology is a classic SD-WAN where my vEdges have 2 external interfaces inside VPN 0 (one for MPLS and another for Internet connectivity). I've created a Feature template for such an interface but vManage allows me to use this template only for one of external interface. 

As the picture shows, I selected "HQ-vpn0-EX-IF" template for my first VPN 0 interface but it grayed out for my second VPN 0 interface. 

Despite that the official deployment guide on Cisco website creates one template for MPLS interface and another template for Internet, I'm curious to know if my method is valid.

And after all, do I need to create a separate template for every VPN interface?! If so, then what is the benefit of creating a template when I need to create a separate template for any interface? I would prefer to directly configure interfaces one by one rather than creating additional overhead by pre-configuring a template!

Feature template which is used cannot be attached with in the same device template, but can be re used in another device template.
