Relume and Webflow: Managing Pages and Updates Efficiently

Hi ! Maybe someone can help me : if I create a sitemap and wireframes on Relume, then I export then to Webflow. Once it has been done, I publish my website. What if I need then to create a new page : can I do it through an update of my project on Relume ? Or do i have to do it directly in Webflow ? And if I need to change something on an existaing page (add a new section for example), can I do it through Relume or i have to do it directly with Webflow ? Thanks in advance
