Hey there @YanivA,
Welcome to the community.
I see what you are trying to achieve. For this, the only solution I can think of is purely based on coding and you'll probably need a developer to get the task done.
1) Duplicate the header three times
2) Modify the header as you want
3) Hide all the headers and show only the one that corresponds to that page.
Hope this gives you some directions.
You can message me if you need my help regarding this.
