Hi @peterburgey,
Thanks for using Shortcoder.
I’m sorry to say that this feature is not supported considering it is not safe to display query value directly on the page. Users may execute malicious code which will execute directly on the page.
I would suggest writing your own shortcode using PHP so that you can clean the query value before working with it – https://codex.wordpress.org/Shortcode_API
Thanks,
