Is it possible to only change something on ONE page, or set pages?

The free version doesn’t have this feature.

Ok, but the pro does?

I see post type on the screen capture, but wasn’t sure if I can do this on only ONE particular page or post for instance… THANKS!

If you can define pattern to match the URL and that definition won’t match any other URL, then use the pro will do what you describe. The Querystring filter is how you provide a simple pattern to match e.g. /match-this-url/. Just make sure the match is unique e.g. /match-this-url/and-not-this/ will still match because it contains /match-this-url/.

For additional questions about the pro version, please go to the pro version’s support page:
