On my side, I started using template together with a x-callback-url shortcut, so you can also set options like pinned, on the agenda or not, expanded or collapsed that can’t be set using the template only.
However since we can place only one shared_content shareholder I find it easier to just use the “text” parameter and basically create the “template” all through the shortcut. So it makes it more interactive as I can ask for as many inputs as I want, combine them with the text functions of shortcuts app and feed it to agenda through the x-callback-url. So in the end I dont need the template feature anymore.
The other nice thing using shortcuts with the x-callback-url feature is you can create an event in the calendar at the same time and link it to the note as well as reminders all in one action.
