Sites pause/unpause specific campaign only

Hi, I'm trying to pause sites on a specific campaign with this endpoint:

https://backstage.taboola.com/backstage/api/1.0/{network-account-name}/campaigns/{campaign-id}

I can see sites paused (they are reflected after 20 min to dashboard) but they result blocked as "Account Level" and I can't unpause them with backstage.
How could I block sites for that campaign only?
Furthermore how could now unblock sites blocked on Account Level?
Thanks
