I have a org-capture template like this:
```
(setq org-capture-templates
        (append '(("w" "org-drill [w]ords"
                   entry (file my-org-drill-words-file)
                   "* %i :drill:
:PROPERTIES:
:DRILL_CARD_TYPE: %^{Drill Difficulty|simple|twosided|multisided|hide1cloze}
:END:

%?

%c
"
                   :empty-lines 1
                   ))
                org-capture-templates))
```
I want to apply a function on `%i` to make it lowercase.
Like `(lowercase %i)` ?
