Different navigation button on every page

Site URL: https://qerkoweb.squarespace.com

Hey guys,

i have the product page with 3 same-level main pages. You can browse there using 3 links in navigation. 
What i need to do, is make different button link for every page, because i need navigate visitors of website to different places depending on who is the user.

3 main pages and types of visitors:
Pro uživatele (For users) – http://onelink.to/s5tgqq (leading to different stores depending on platform)
Pro restaurace (For restaurants) – typeform script
Pro obsluhu (For waiters) – same typeform script
