Content Staging : How do I have a different Pages setting for my Staging environment?

[#1]

I'm working on a site enhancement where I am stripping out an existing theme's styles and scripts and re-writing them so I can chunk out the codes I need for a template specifically to improve page load.

The existing site now has 10 stylesheets and 10 scripts imported from my Settings > Pages screen. I'm trying to remove these additional stylesheets and scripts so I won't have a clashing of styles but I can't find a way to remove it from my Settings.

Does anyone know a way around this?

At the very top of the settings > pages you'll see a place to select the domain. You should be able to find a hubspot domain that you can use.

The alternative way, is the remove the style sheets from your settings and use them on your templates only.

Make sense?
