[Plugin: GD Star Rating] Vote on Category

Hey, i wondered if it’s somehow possible to vote on categories? Right now i have called wp_gdsr_render_article(); on the category pages, but it’s like voting on the last article in the category. So when i post a new post the votes are reset, or they aren’t reset but they won’t affect the overall category rating until the number of votes has exceeded the post with the most votes in said category. And even then the old votes won’t affect the new overall rating.
