Unable to stage CMS without paying for CMS hosting first

I have a website that is published to a custom domain as well as to .webflow.io and it is hosted on the basic plan. I would like to start working on staging a blog for this website on the .webflow.io domain and when I’m ready to publish to the custom domain pay for the CMS hosting and get it live. Unfortunately Webflow won’t let me do that. Any workaround or maybe Webflow team has something to say?
