I created one template NPC for the encounter but unfortunately, I must update all skills and items individually. In my example: I decided to create a group of 5 Thugs (3 with melee weapons, 1 archer, 1 leader) - they should share almost all stats and skills except 1-2 archetype specific.
In my opinion, simple copy NPC feature will be very useful in similar cases
