What's the best way to save a webpage as a template in a theme? For example, a client built out a webpage using highly-configured theme modules and wants that saved as a template (does not want to just clone that page). Would you use the developer tools to copy the hubl code of each section and paste it into a template file, start from scratch in a template file and just code all the module options to match what the client created, or is there an easier way? Is the API response for fetching a page in a format that could easily be converted to a template?
