We are updating our website and help center and want to apply a new theme to along with some of the personalized styling settings. We know that it's posslble to create a sandbox version of the help center so the changes are not published live. https://help.zoho.com/portal/kb/articles/customizing-help-center-themes-in-the-sandbox  

My question is, it doesn't seem possible to save a draft version of the sandbox and then revisit it at a later time. All the customization needs to be done in one shot and published or the changes are lost. This is not very ideal as we have stakeholders to show the changes to in order to approve for publishing. Is there a place where changes to the look of the help center can be saved prior to publishing?
