Protoyping issues

Hello, 

I am new here..., I am finalising my thesis this weekend. Hope this community can help me.

I want to know how I can prototype just a small part content of one board to another small part of another board. 

I know how to link one board to one other board, but I want the user can move to directly the right content on another board without scrolling up and down.

I attached a printscreen, hope it is usefull to understand.

thank you very much!
