Hi Tobias,
I asked the developer and he replied this:
I can’t provide specifics on how they might want to implement a solution, as it will depend on their software. However, they’ll most likely want to force processing of their shortcodes using the page_generator_pro_generate_post_args filter, which fires prior to the creation of the generated Page:

I hope it helps, let me know if I have to ask him anything else
Thank you for your time and patience
Thank you so much for you quick response.
Actually there is a free version if you want to check it out https://es.ww.wp.xz.cn/plugins/page-generator/
Anyway I’m going to ask the developer about the function name and let you know.
Cheers
