My bad. I read too fast and thought that you did not want to see the notes that were not created. AFAIK the only way to automatically use a template is with the Daily note or Zettelkasten plugin.
Some time ago there was lots of talk around a way to add a specific template to any new note, but if a plugin was ever developed, I don’t know of it.
Last thought, although it’s still a workaround - the calendar plugin, coupled with periodic notes, allows for a designated template to be used when clicking on a specific day. The nice thing is that the date parsing is done as if you were adding the note on the day you clicked, so things like your snippet would still work in the way you’d expect without modifying them manually.
