I added Transmission, Emission and Alpha to the NW AddPrincipledSetup.
Those are some of the most frequently used maps that where missing. If you are reading this you may know how it helps with frequent loading of maps or in big scenes and you don’t have to respect a rigid naming convention as a bonus.
The modified addon is here:https://blenderartists.org/t/node-wrangler-improvement-extra-maps/1345613
You just need to disable the default one,restart and load this.
FIXED: The AO is not working currently and I asked for help on BA post.
If this gets done too maybe a more experienced user-coder cand submit the code on https://developer.blender.org/
