As the title states, I'm unsure if it is possible to customize the folder Gatsby looks into to generate static pages. Apparently, this seems to be fixed without the ability to change from the pages/ folder. Ideally, this could be changed with something like an environment variable or similar. On the existing docs (https://www.gatsbyjs.com/docs/creating-and-modifying-pages/) nothing like this is mentioned.
Does anybody know if this is possible and I've just missed it somewhere? I've also opened this feature request discussion on the Gatsby GitHub: https://github.com/gatsbyjs/gatsby/discussions/35727
