Hello, this is not a feature we provide “out of the box” but is something you can achieve using code.
By default, you can send a push to everyone you want when you select the checkbox and publish the post.
For your custom solution:
You can use our Data Tags to tag devices when they visit certain posts: https://documentation.onesignal.com/docs/data-tag-implementation
If you want to setup your own button or prompt asking the user if they want to be updated with updates, that would be recommended.
Then when you update the post, you can target users that have that data tag.
You can use the onesignal_send_notification filter to do this: https://documentation.onesignal.com/docs/web-push-wordpress-faq#onesignal_send_notification-filter
With our “filters” API parameter instead of “included_segments”

Feel free to reach us at [email protected] for further assistance.
