[O] is it possible to reuse a capture template expansion?

[Stig Brautaset]

I've got a capture template where I want to prompt for a string and use
it in two places, but I end up being prompted twice. I want a template
something like the below, and be prompted only once each for Title and
Abstract. Is that possible somehow? Any help appreciated.


: * TODO Write %^{Title} Blog post
: #+begin_html
: ---
: title: %^{Title}
: layout: post
: abstract: %^{Abstract}
: ---
: #+end_html
:
: %^{Abstract}
:
: %?
