Include the content of one note in another

Just found this can be achieved a minima, with the use of templates: Templates - how to use?

However, if I’m not mistaken, if I change the template, this change won’t be reflected in the existing notes where I included it.

My request go further than the templates on two counts:

  1. By having a reference in the note, the content could be updated on rendering.
  2. By referencing a note, all the content is also synced across Joplin instances.

Any opinion ?
