1. No, it has to be a Character builder template.
2. I believe so, but it has been quite some time when I did that setup, Component tag is quite deep...
Alternatively, you can try nodes which will give you much more power and can ceratinly do it. Either way you are looking into some work 🙂
Open Hrvoje's file and save the Character template. Now Load Character Template and choose the file you just saved. Make a new Character and in the Template dropdown, the VP_Roadtest will appear.
