You can assign it to a variable that you can later use, for example:[selectedGenre=genre.selectOne].

What you can do is this:

// Lists Editor
movieTitlePrompt
  instruction = Make a title for a [g = genre.selectOne] movie with a length of [l = length.selectOne] and an age rating of [ar = ageRating.selectOne]. Only include the title, nothing else. No subtitle.

title
  [ai(movieTitlePrompt)]
// ---
// HTML
<p>Title: [title]</p>
<p>Genre: [g]</p>
<p>Length: [l]</p>
<p>Rating: [ar]</p>
