Editing dynamic data (custom types) in a plugin

unfortunately I haven’t got a response from @k6c8e4 . It’s been a while so I don’t remember exactly why I wanted this.

Based on the lottemint’s post, one can create a custom thing in a plugin, which is fantastic. What I wanted was a way to dynamically change the JSON structure in run mode, but as far as I know, this can’t be done.
