Display category name in Guide's search placeholder

Hi…I currently use dynamic content to display placeholder text in the search field on the category page. The placeholder currently displays “Search this category” in the selected language. To improve usability, I'd like to display the designated category name in the placeholder. For example if the user selects a category in guide called ProductX, the search placeholder should display “Search ProductX” in the appropriate language. Does anyone know how this can be accomplished? Dynamic content only seems to support the addition of user- and ticket-related placeholders.

Thanks

Stefano
