I don't really know where yo put this. Hopefully this is correct.
The document is created in the basic Gutenberg WordPress editor.
Is there a way to create a custom field set (group) for a custom post type, in which if you fill in the custom fields, those fields update certain words in the Gutenberg editor.
Custom field: [NAME] = Steevn
This is the document of [NAME].
Text on the frontend:
This is the document of Steevn.
Hopefully this is possible and thanks beforehand for the help!
