Global Branding Assets

Would you please make it possible to use global branding assets everywhere in an account? I would like my brand colors and fonts to be automatically available for pages, emails, forms, etc. instead of having to reset them every time I create a new page.

I know I can duplicate a page and get the settings that way, but if I want to set up an entirely new format, I have to go through and redo all of my fonts and colors. That takes time, which is annoying.

Thanks. :)
