Filter ‘text before form’ output?

Hi, I’m wondering if there’s any simple filter function that can be added, where I can execute a shortcode inside the ‘before form’ text? I’ve registered a shortcode to output the site title and would like to put that in the ‘before’ text programatically (so can be deployed easily for multiple sites).

Tried

add_filter( 'genesis-enews-extended-args', 'do_shortcode' );

but no joy. Please let me know if there’s a solution, thanks!
