Adding reactpress app to multiple pages

I am trying to add Reactpress app on multiple pages.

Is there any way to add it to the pages which contains particular slug in the URL? I understand you can manually add slugs for each page in the reactpress app however we have 300+ pages. Just wanted to know if there’s a way to add it dynamically something like a shortcode?

Appreciate if anyone has experienced the same situation and has any workaround.

Thanks Sau
