I want to capture several tasks that will repeat annually from the date on which they are captured.

So, I did:

(setq org-capture-templates
        '(("a" "TODO Item that repeats annually" entry (file+headline "~/Documents/todo.org" "Annual")
           "* TODO %?\n SCHEDULED: %t")))

This adds a TODO with scheduled date as today. How do I get '+1y' added to scheduled?

On a more general note, what should the capture template be with schedule for tomorrow, tomorrow recurring annually, etc.?
