How to pull in all the Demo Header content

I know I won’t be able to use all the Header Demos, but I’d like to experiment to see which one I like with a different demo. I have no way of using other ones from demo without first importing the actual related demo. I was hoping you can export all the ones that you showed in the screenshot and attach it as a text file with each one indicating which is which. I think this will be very useful to me if I were to play around with the theme’s header demo content w/ different variations of the theme demo. Like I may not like the new magazine header and rather use a different one from a different demo. That’s how and why I’ll need to have them all, even though I’ll only use one. Hope that makes more sense.
