Hi, I'm using again this wonderful system to create sitemaps, and create a sitemap with all the urls from my website, a total of 5025 urls. And my question is this, when I want to update my sitemap and add new urls, I have to rebuild again sitemap from 0? If I have 30 new post, is there any way to add only those new 30 post and not those that already exist? Or every time I want to update my sitemap will be created over the past 5025 plus new urls url? I do not know if I could properly explain greetings and thanks. sorry for my English
