Link directly to add listing page into…

Hello, I would like to create a link in the empty categories that says create listing in this category. Is there a parameter I can add to the add-listing url to go post an ad directly into that category? The end result would be that when someone clicks into an empty category (no ads) there will be a link to allow them to post into that category without having to select the category during the add-listing process as they may forget the name if there is a long list of categories/subcategories. Thank you Brian
