[support] move article after creation in order

Hello, I have a weird issue. I have created a few articles and now want to move one of these in between of the others. Like: Article1 Article2 Article3 Article_new to: Article1 Article2 Article_new Article3 but I cannot find a way to move the article after it is created. Please, point me to the right direction. Thanks in advance. Best Regards, Thomas
