Dynamic Append Fields

Hi Everyone, 

I am trying to do a dynamic append fields but can't figure out how to do it in Alteryx:

The source looks like this: 

The column field determines in which column the name row belongs to. 

And desired results: 

Challenge: The numbers of columns needed to be created is not known in advanced as the source varies - so I cannot put a certain amount of Append Fields or Text to Columns tools in advance. 

How can I create the same result dynamically. 

Thank you in advance for your help.
