About custom privacy on facebook. Business page?

[Hannah]

Hi. I know you can choose specific people to show your posts thru custom privacy.
But I find it impossible with business pages like Coca Cola for example?

I've been following some business facebook pages of several companies.
They made a winning event that you have to share their post on your timeline.
But I have more shared posts from other companies so I don't want to look like one of those-
who follow companies only because of the prize.

Then I saw these people who KEEP winning stuff and when I visit their page, they rarely have shared posts. How is this possible?

Is there a way that I can share the post and they would see it on my page and others don't?
Not a person, but companies page when they visit me to check if I shared! Thanks!
