Hi Jared,
Create draft pages > Once you are happy with the layout, use Cornerstone Template function to save this page as a Cornerstone Template and apply to the original page. That way you will replace the content on the original page while working in a draft page.
Cornerstone Template
To do that go to Cornerstone > Templates > Save Template > REMEMBER TO RE-NAME IT > Save to library
Access your Page > Templates > Select the Page you save it > Insert > Save.
Hope that helps,
Joao
