Hello,
thanks a lot, especially for the updated diagram.
I’ll definitely try to implement this! For now I found a very inelegant way to achieve what I want using Human tools. Out of lack of time I couldn’t do it the pretty way with my own C# component (just not enough practice with C# yet…) but in the later stages of this project I will remedy that. 
I’ve come up with this, so the user has to actually type in the user data.
At a later point, I’ll try to use your code and advice to make a component that creates the user data depending on various inputs that are more easily understandable for a user.
